Abstract:
The discovery and application of ynamide coupling reagents is highlighted with a brief summary of the development history of coupling reagents in amide and peptide synthesis. As novel coupling reagents, ynamides are not only effective for simple amide and dipeptide synthesis but also can be used for peptide fragment condensation. More importantly, no racemization was detected during the activation of α-chiral carboxylic acids by employing ynamide coupling reagents.1 Introduction2 Carbodiimide Coupling Reagents3 Uronium/Guanidinium Salt Coupling Reagents4 Phosphonium Salt Coupling Reagents5 Ethoxyacetylene as a Coupling Reagent6 Ynamine Coupling Reagents7 Ynamide Coupling Reagents8 Summary and Outlook

Abstract:
The present review summarizes primary publications on the cross-dehydrogenative C–O coupling, with special emphasis on the studies published after 2000. The starting compound, which donates a carbon atom for the formation of a new C–O bond, is called the CH-reagent or the C-reagent, and the compound, an oxygen atom of which is involved in the new bond, is called the OH-reagent or the O-reagent. Alcohols and carboxylic acids are most commonly used as O-reagents; hydroxylamine derivatives, hydroperoxides, and sulfonic acids are employed less often. The cross-dehydrogenative C–O coupling reactions are carried out using different C-reagents, such as compounds containing directing functional groups (amide, heteroaromatic, oxime, and so on) and compounds with activated C–H bonds (aldehydes, alcohols, ketones, ethers, amines, amides, compounds containing the benzyl, allyl, or propargyl moiety). An analysis of the published data showed that the principles at the basis of a particular cross-dehydrogenative C–O coupling reaction are dictated mainly by the nature of the C-reagent. Hence, in the present review the data are classified according to the structures of C-reagents, and, in the second place, according to the type of oxidative systems. Besides the typical cross-dehydrogenative coupling reactions of CH- and OH-reagents, closely related C–H activation processes involving intermolecular C–O bond formation are discussed: acyloxylation reactions with ArI(O2CR)2 reagents and generation of O-reagents in situ from C-reagents (methylarenes, aldehydes, etc.).

Abstract:
The lateral giant axons of the crayfish nerve cord are composed of segments contributed by each ganglion, which are electrotonically coupled by way of gap junctions. We have investigated the involvement of protein residues in regulating the resistance of crayfish junctional channels by determining effects of group-specific protein reagents. When applied to well-coupled axons, the sulfhydryl group reagents N-ethylmaleimide (NEM) and diamide uncoupled the segments; junctional resistance (Rj) was increased without changing membrane resistance or axoplasmic pH (pHi). The uncoupling produced by NEM could be reversed by alkalinization of the cytoplasm (addition of ammonium chloride to the external medium). Another sulfhydryl reagent (p-chloromercuribenzoic acid) increased Rj to a lesser extent. A disulfide reagent and three amino and three carboxyl group reagents had no effect on the Rj of these axons. The effect of group-specific reagents on partially uncoupled axons was tested by applying the drugs to axons previously exposed to weak acids. N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline recoupled partially uncoupled axons by decreasing Rj and prevented subsequent uncoupling of the junction by low pHi. Another carboxyl group reagent, as well as sulfhydryl and amino group reagents, either had no effect or uncoupled the axons further by increasing Rj. These experimental results suggest that amino acid residues, possibly containing carboxyl and sulfhydryl groups, control the opening and closing of junctional channels and may thus be associated with the channels' active sites.

Abstract:
Organometallic compounds derived from tin, boron, and zinc, have been used extensively in transition metal-catalysed cross-coupling, and continue to hold status as the go-to reagents to form new carbon-carbon bonds. Recently, organosilicon compounds have emerged as an attractive alternative to these established reagents, benefitting from low toxicity, low cost, and general ease of handling. While the fundamental reactivity of arylsilane reagents (Ar-SiR3) is well known, their role in transition metal-catalysed reactions is generally less well studied. This thesis comprises an investigation into the effect of ortho-substitution of these arylsilane reagents, and specifically, their application in gold-catalysed direct arylation. In Chapter 2, the transmetalation of these reagents to gold(III) is assessed using a combination of in situ reaction monitoring coupled with kinetic simulations. This allowed a scale of reactivity to be constructed for a range of structurally diverse arylsilanes, and uncovered that more sterically hindered arylsilanes actually exhibit accelerated rates of transmetalation. In Chapter 3, the reactivity of ortho-substituted arylsilanes in gold-catalysed arylation is addressed. The majority of arylsilanes tested in the previous chapter were found to be unable to undergo coupling, despite the viability of transmetalation having been demonstrated. Slight modification of the ortho-substituent, to incorporate a tethered ligand, was found to have a dramatic effect on reactivity, and allowed the coupling of a variety of substrates. The nature of the ligand, as well as the substitution of the tether was found to have a significant impact on the rate of coupling. Chapter 4 describes the way in which the reactivity of ortho-substituted arylsilanes might be exploited in a 'Catch and Release' protocol for catalyst recovery. This aims to combine the established benefits of homogeneous and heterogeneous catalysis to offer an alternative to current methods of catalyst recycling in industrial chemistry. A number of different 'Catch and Release' mechanisms were considered, and the validity of the concept was demonstrated in a monophasic system.

Abstract:
Les réactions de couplage croisé catalysées par des métaux de transition permettant la formation de liaisons C-C et C-hétéroatome sont à la base de la synthèse d’intermédiaires clefs pour la chimie pharmaceutique, la chimie supramoléculaire et la chimie des matériaux. Cependant, certains catalyseurs métalliques utilisés sont reconnus comme étant assez coûteux ou toxiques. Le développement de catalyseurs alternatifs peu coûteux et écologiques, tels que les catalyseurs à base de cobalt qui ont déjà montré leur efficacité pour la formation de liaisons C-C, fait donc l’objet d’études. Nous avons décidé d’utiliser des organozinciques aromatiques fonctionnalisés, obtenus facilement à l’aide d'une réaction catalysée par CoBr2, dans des réactions de couplage catalysées par CoBr2 avec des chloro-diazines et -triazines aboutissant à la synthèse d’aryldiazines et -triazines. Des organozinciques benzyliques ont également pu être utilisés dans ces réactions permettant la synthèse de benzyltriazines. Nous avons également envisagé l’utilisation d’autres types de substrats. Des réactions de couplage catalysées par CoBr2 entre des organozinciques aromatiques et des méthylthiopyrimidines ou le 2- méthylthiobenzo[b]thiazole ont ainsi été réalisées, conduisant à la synthèse de 2,4- diarylpyrimidines ou de 2-arylbenzo[b]thiazoles. Nous avons également étudié la réactivité des dérivés du benzonitrile dans les couplages directs catalysés par CoBr2 avec des halogénures aromatiques basés sur l’activation de la liaison C-CN pour former des biaryles. Enfin, des réactions de couplage croisé C-N entre des halogénures aromatiques et l’aniline conduisant à la synthèse de diarylamines ont été étudiées<br>Transition metal-catalyzed cross-coupling reactions allowing the formation of C-C or C-Heteroatom bonds underlie the synthesis of key intermediates for pharmaceutical, supramolecular chemistry and material sciences. Thereby, the development of these methodologies is prominent and an increasing number of studies are devoted to these processes. However, some metallic catalysts are known to be rather expensive or toxic. Consequently, the development of alternative sustainable catalysts such as cobalt or ironbased catalysts has been studied over the past few years. Cobalt-catalysts have been little-used although they have shown to be effective for various C-C bond forming reactions. Functionalized arylzinc reagents can be readily obtained from the corresponding arylhalides using a CoBr2-catalyzed reaction. First we envisioned using these arylzinc reagents in CoBr2-catalyzed cross-coupling reactions with chlorodiazines and chlorotriazines leading to aryldiazines and aryltriazines. Benzylzinc reagents had also been used in these reactions and we synthesized various benzyltriazines in this manner. We also studied whether we can use other kind of substrates in these reactions. Thus, we performed CoBr2-catalyzed cross-coupling reactions between arylzinc reagents and methylthiopyrimidines or methylthiobenzo[b]thiazole derivatives leading to 2,4-diarylpyrimidines and 2- arylbenzo[b]thiazole. Then, we studied the reactivity of benzonitrile derivatives in direct cross-coupling reactions with arylhalide based on C-CN bond activation using CoBr2 as catalyst. Finally, we also carried out the study of CoBr2-catalyzed C-N cross-coupling reactions for the synthesis of diarylamines

Abstract:
The first part of the thesis presents the KMnO4/ carboxylic acid/ organic solvent which is a powerful reagent for C-C bond formation, aryl coupling reactions and enone oxidation. The a&cent<br>-acetoxylation of enones and the a-acetoxylation of aromatic ketones were carried out with potassium permanganate and acetic acid, in which acetoxylation products were obtained in 74-96% yields. The same reaction was carried out with carboxylic acids other than acetic acid, which furnished corresponding acyloxy ketones with the same regioselectivity. For the first time, formyloxylation products were synthesized in a 61-85% yield by using formic acid. The potassium permanganate and acetic acid method was also used for aryl coupling reactions. The reaction of arylboronic acids and aryl hydrazines in benzene with potassium permanganate and acetic acid in turn furnished biaryls in a 85-96% yield. We showed that potassium permanganate/carboxylic acid/organic solvent behaves as manganese(III) acetate. In the second part of the thesis, ipso-nitration of arylboronic acids with AgNO2/ TMSCl was performed. Nitration of aromatic compounds is one of the most extensively studied reactions, and nitroaryl moieties play key roles in the physical and chemical properties of many target molecules in organic synthesis. For electrophilic nitration of aromatic compounds, a wide variety of reagents are available to date. Most of them are very strong nitrating agents and often lead to further nitration and mixture of isomers. Since most nitrating agents are oxidants, oxidation of other functional groups can also occur, giving a mixture of products. Thus, a search for milder and selective nitrating agents is a good research goal. In this work, we aimed to apply AgNO2/ TMSCl system to ipso nitration of arylboronic acids.

Abstract:
Phosphine complexes of nickel and palladium provide the best catalysts for the homogeneous catalysed carbon-carbon bond forming reaction between an organometallic nucleophile and an organic electrophile. Use of a homochiral ligand on the catalyst can lead to stereoselectivity in the cross-coupling reaction, with high ee's of coupled product being obtained. The processes of selectivity in the transmetalation step of the catalytic cycle have not been elucidated and the initial aim of the project was to study these processes. Initial experiments using organotin derivatives as the organometallic nucleophile highlighted the problems of selectivity and the forcing conditions needed in the attempted transfer of a benzyl group from the tin to the palladium catalyst. The compounds [8- (dimethylamino)-1-naphthyl]methyldiphenyltin (60) and [2-((dimethylamino)methyl) phenyl]methyldiphenyltin (70) were prepared and their reactivity in the palladium catalysed cross-coupling with 2-furoyl chloride, to give 2-benzoylfuran, was investigated. These molecules were found to undergo facilitated transfer of a phenyl group compared to transfer from control molecules. The effect was tested and attributed to the internal nucleophilic attack at the tin atom by the lone pair on the nitrogen atom. The compound [2- ((dimethylamino)methyl)-3-trimethylsilylphenyl]methyldiphenyltin (79) was prepared to test the effects of steric buttressing within the molecule, but was found to be of the same order of magnitude of reactivity as (60) and (70). All three molecules showed a reactivity of at least an order of magnitude greater than control compounds. The effect did not prove applicable to the transfer of a benzyl group or in other coupling reactions. The effect of palladium ligation was tested and the ligand triphenyl arsine found to increase the rate of the coupling reaction. The two facilitating processes were found to work in a co-operative fashion, giving a rate enhancement of ca. one hundredfold over control reactions. The nickel catalysed cross-coupling of α-substituted sp<sup>3</sup> hybridised Grignard reagents with allylic esters was attempted, but proved unsuccessful. Stoichiometric reactions with nickel complexes were also found to be unsatisfactory in yielding coupled products. The synthesis of α-substituted diorganozinc reagents was attempted, but furnished only homocoupled products. The reaction of dibenzylzinc with aldehydes was found to proceed in the absence of catalyst, highlighting the reactivity of a benzylzinc moiety.

Abstract:
Activated esters, e.g. triflates, sulfonates, nonaflates and phosphates are excellent electrophiles for a variety of cross-coupling reactions. However, other phosphorus-based esters have received little attention in these protocols. This thesis discusses the synthesis and cross-coupling chemistry of vinyl phosphinates, a new class of electrophilic species. A simple model vinyl phosphinate, N-(tert-butyloxycarbonyl)-4,5,6,7-tetrahydro-1H-azepin-2-yl-diphenylphosphinate, was prepared in excellent yield from commercially available caprolactam. A screening study identified Suzuki cross-coupling conditions under which this phosphinate smoothly coupled with a variety of electron-rich, electron-poor and sterically-hindered boronic acids. The scope and limitations of this chemistry were investigated and a variety of electron-withdrawing nitrogen protecting groups, e.g. Boc, CO(_2)Ph, C0(_2)Bn and Ts could be used without problem. However, electron-donating protecting groups, e.g. Me and Bn proved unsuccessful. Additionally, where seven and eight-membered ring lactam phosphinates coupled efficiently, five and six-membered ring derivatives proved largely unsuccessful. Relative reactivity studies were carried out with N-phenyloxycarbonyl-2- (diphenylphosphinoyloxy)-3,4-dihydro-6-bromoquinolone and indicated that the reactivity of vinyl phosphinates lies between that of aryl chlorides and aryl bromides in the Suzuki reaction. Attempts to improve the efficiency of the cross-coupling of this substrate using DoE and PCA modelling was attempted, but was largely unsuccessful. Studies towards the total synthesis of Lennoxamine via a cross-coupling reaction between a benzazepine-derived vinyl phosphinate and 2,3-dimethoxy-N-(2'-phenylpropan-2-yl)-6-(tributylstannyl) benzamide were commenced. Synthesis of the stannane was achieved in high yield via a directed metallation strategy. Unfortunately, preliminary attempts to cross-couple this stannane with N-(benzyloxycarbonyl)-4,5,6,7- tetrahydro-1 H-azepin-2-yl diphenylphosphinate in a model reaction were unsuccessful. Synthesis of the desired benzazepine phosphinate fragment proved more difficult and although progress has been made, this work remains unfinished. Additionally, treatment of N-([4'-methylphenyl]sulfonyl)-2-oxo-azepane with LDA/TMEDA in the presence of diphenylphosphoryl chloride afforded the sultam 1,2,3,4-tetrahydro-7-methylazepino[1,2-b][1,2]benzothiazole-10,10-dioxide in moderate yield. A range of aryl sulfonamides could be used affording the corresponding sultams in moderate yields.

Thesis advisor: James P. Morken<br>Described herein are three distinct projects centered on the formation and use of carbon-boron bonds. In the first, the enantioselective platinum-catalyzed 1,4-diboration of trans-1,3-dienes is advanced in both selectivity and scope through the development of a novel class of electron rich chiral monodentate phosphines. Under the action of the new ligands, highly selective diboration is maintained at reduced loadings of catalyst. Secondly, enantioenriched 1,2-bis(pinacol boronates) are engaged in regioselective Suzuki-Miyaura cross-coupling with aryl and vinyl electrophiles. A tandem diboration cross-coupling sequence is successfully implemented to afford homobenzylic and homoallylic pinacol boronates directly from terminal olefins, which subsequently undergo oxidation, amination or homologation of the remaining carbon-boron bond to arrive at a range of enantioenriched products. Lastly, aryl electrophiles containing tethered allylboronate units undergo efficient intramolecular coupling in the presence of a chiral palladium catalyst to give enantioenriched carbocyclic products<br>Thesis (PhD) — Boston College, 2014<br>Submitted to: Boston College.

Abstract:
During the last decade, GlaxoSmithKline Pharmaceuticals (GSK) has carried out much of the seminal work in the area of micro fluidics and micro flow assay for lead optimisation. It has pioneered and built an in-house micro fluidic system for drug discovery. The huge and diverse advantages of this approach come from its miniaturised nature and its scale, which makes it easily automatable. As a result of its miniaturised nature it allows for greater control over heat and mass transfer, along with lower consumption of reagents (both chemical and biological) and solvents, less waste generation and decreased exposure to potentially toxic materials. But for a pharmaceutical company, the main advantage of this technology is the capability of coupling a fast microfluidic chemistry generator with a modern compatible miniaturised screening technique to generate instant biological information (i.e. the assay results) in “real time” that can be used to refine the chemistry (closing the feedback loop) and therefore allowing for a much faster lead optimisation. We will review some of the efforts within GSK towards this pioneering work in the development of miniaturised chemistry platforms capable of performing multiple functions such as synthesis, separation, quantification and screening.
