Abstract:

Sunggak Kim of KAIST reported (Synlett 2009, 81) an improved protocol for the one-carbon free radical homologation of an iodide such as 1 to the nitrile. Primary, secondary, and tertiary iodides work well. We described (Tetrahedron Lett. 2009, 50, 2462) a procedure for the one-carbon homologation of a halide 4 directly to the benzyl ether 6. Bin Xu of Shanghai University showed (Chem. Commun. 2009, 3246) that conversion of a ketone 8 to the 1,1-dibromoalkene set the stage for the net one-carbon homologation to the amide 9. A. Fernández-Mateos of the Universidad de Salamanca uncovered (J. Org. Chem. 2009, 74, 3913) a powerful new branching reaction, condensing the more substituted center of an epoxide 10 with a nitrile 11 to deliver the adduct 12. Useful diastereocontrol was observed with cyclic epoxides. Uli Kazmaier of the Universität des Saarlandes optimized (Adv. Synthy. Cat. 2009, 351, 1395) a Mo catalyst for the hydrostannation of a terminal alkene 13 to the branched product 14. Dong-Mei Cui of the Zhejiang University of Technology and Chen Zhang of Zhejiang University (both in Hangzhou) developed (Chem. Commun. 2009, 1577) a complementary procedure, converting the terminal alkene 15 into the branched alkenyl tosylate 16. The Wittig reaction is notorious for racemizing sensitive aldehydes. Hélène Lebel of the Université de Montréal demonstrated (Organic Lett. 2009, 11, 41) a simple one-pot protocol for sequential oxidation and homologation of 17 that preserved the integrity of the adjacent stereogenic center. The stereocontrolled construction of trisubstituted alkenes is still a major issue in organic synthesis. Giancarlo Verardo of the University of Udine established (J. Phys. Org. Chem. 2009, 22, 24) that the α-diazo ester 19, readily prepared directly from the simple ester, was converted by I2 to the alkene 20 with high geometric control. Condensation with the Ohira reagent 22 is often the method of choice for converting an aldehyde into the homologated alkyne. Hubert Maehr and Milan Uskokovic of Bioxell and Carl P. Schaffner of the Waksman Institute described (Syn. Commun. 2009, 39, 299) an optimized, scalable procedure for the in situ preparation of 22 and the conversion of 21 to 23. Note, again, that the sensitive stereogenic center adjacent to the intermediate aldehyde was not epimerized under the reaction conditions.

Abstract:

The pentacyclic alkaloid manzamine A 4, isolated from a sponge collected in the Okinawa Sea, displays a range of antibacterial, anticancer, and antimalarial activity. The preparation of 4 reported (J. Am. Chem. Soc. 2012, 134, 17482) by Darren J. Dixon of the University of Oxford showcases the versatility of the nitro group in organic synthesis. The nitro alkene 2 was prepared from the commercial bromide 5. Displacement with acetate followed by Swern oxidation led to the aldehyde 6, which was condensed with nitromethane to give 2. Lactam 1 was an intermediate in Professor Dixon’s synthesis (Org. Highlights May 3, 2010) of (–)-nakadomarin A. Lactam 1 was prepared from the tosylate 7, which was derived from pyroglutamic acid. The addition of 1 to the nitroalkene 2 delivered 3 as the dominant diastereomer of the four that were possible. Mannich condensation with formaldehyde and the amine 12 gave 13. The nitro group of 13 was removed by free radical reduction. Exposure of the reduced product to trimethylsilyl iodide gave, via ionization of the ketal, the primary iodide, which was carried onto the nitro compound 14. Dibal selectively reduced the δ-lactam. Partial reduction of the γ-lactam then gave an intermediate that engaged in Mannich condensation with the nitro-activated methylene to give 15. Although there are many protocols for the conversion of a nitro compound to a ketone, most of those were not compatible with the functional groups of 15. Fortunately, Ti(III) was effective. Ce-mediated addition of the Grignard reagent 16 to the ketone followed by deprotection and protection then delivered the silyl ether 17. Remarkably, the ketone 17 could be deprotonated and carried on to the enol triflate 18 without eliminating the TMSO group. Coupling with the stannane 19 then completed the synthesis of manzamine A 4. One-carbon homologation of 18 led to ircinol A, ircinal A, and methyl ircinate (not illustrated).

Ilhyong Ryu of Osaka Prefecture University devised (Synlett 2010, 2014) a practical procedure for the free radical addition of HBr to an alkene 5. Tetsuo Ohta of Doshisha University showed (Tetrahedron Lett. 2010, 51, 2806) that a Ru catalyst could add an aromatic acid to the internal carbon of a terminal alkene 7. Noriki Kutsumura and Takao Saito of the Tokyo University of Science found (Org. Lett. 2010, 12, 3316) conditions for bromination/dehydrobromination to convert 10 to 11. Tsuyoshi Taniguchi of Kanazawa University oxidized (J. Org. Chem. 2010, 75, 8126) the alkene 12 to the nitro alkene 13. Professor Taniguchi added (Angew. Chem. Int. Ed. 2010, 49, 10154) methyl carbazate to 14 to give the β-hydroxy ester 15. Philippe Renaud of the University of Bern effected (J. Am. Chem. Soc. 2010, 132, 17511) the free radical homologation of 16 to the azide 18. Daniel P. Becker of Loyola University described (Tetrahedron Lett. 2010, 51, 3514) the elegant diastereoselective Pd-catalyzed bis-methoxycarbonylation of 19 to the diester 20. Matthew S. Sigman of the University of Utah established (J. Am. Chem. Soc. 2010, 132, 13981) the oxidative Heck arylation of 21 to 23. F. Dean Toste of the University of California, Berkeley, found (Org. Lett. 2010, 12, 4728) that the intermediate in the gold-catalyzed alkoxylation of 24 could couple to an aryl silane 25 to give 26. Chun-Yu Ho of the Chinese University of Hong Kong used (Angew. Chem. Int. Ed. 2010, 49, 9182) a Ni catalyst to add styrene 27 to the alkene 24. Masahiro Miura of Osaka University effected (J. Org.

Abstract:

Several remarkable one-carbon homologations have recently appeared. André B. Charette of the Université de Montréal reported (J. Org. Chem. 2008, 73, 8097) the alkylation of diiodomethane with alkyl iodides such as 1, to give the diiodoalkane 2. Carlo Punta and the late Ombretta Porta of the Politecnico di Milano effected (Organic Lett. 2008, 10, 5063) reductive condensation of an amine 3 with an aldehyde 4 in the presence of methanol, to give the amino alcohol 5. Timothy S. Snowden of the University of Alabama showed (Organic Lett. 2008, 10, 3853) that NaBH4 reduced the carbinol 7, easily prepared from the aldehyde 6, to the acid 8. Ram N. Ram of the Indian Institute of Technology, Delhi found (J. Org. Chem. 2008, 73, 5633) that CuCl reduced 7 to the chloro ketone 9. Kálmán J. Szabó of Stockholm University extended (Chem. Commun. 2008, 3420) his elegant work on in situ borinate formation, coupling, in one pot, the allylic alcohol 10 with the acetal 11 (hydrolysed in situ) to deliver the alcohol 12 as a single diastereomer. Samir Z. Zard of the Ecole Polytechnique developed (J. Am. Chem. Soc. 2008, 130, 8898) the 6-fluoropyridyloxy ether of 13 as an effective radical leaving group, enabling efficient coupling with 14, activated by dilauroyl peroxide, to give 15. Shu Kobayashi of the University of Tokyo established (Chem. Commun. 2008, 6354) that the anion of the sulfonyl imidate 17 participated in direct Pd-mediated allylic coupling with the carbonate 16. The product sulfonyl imidate 18 is itself of medicinal interest. It is also easily converted to other functional groups, including the aldehyde 19. Jianliang Xiao of the University of Liverpool found (J. Am. Chem. Soc. 2008, 130, 10510) that Pd-mediated coupling of an aldehyde 21 in the presence of pyrrolidine led to the ketone 22. The reaction is probably proceeding via Heck coupling of the aryl halide with the in situ generated enamine. Alois Fürstner of the Max Planck Institut, Mülheim observed (J. Am. Chem. Soc. 2008, 130, 8773) that in the presence of the simple catalyst Fe(acac)3 a Grignard reagent 24 coupled smoothly with an aryl halide 23 to give 25.

Abstract:

In the context of peptidyl ketone synthesis, Troels Skrydstrup of the University of Aarhus developed (J. Org. Chem. 2008, 73, 1088) the elegant SmI2-mediated conjugate addition of acyl oxazolidinones such as 1 to acceptors such as 2. Sadagopan Raghavan of the Indian Institute of Chemical Technology, Hyderabad reported (Tetrahedron Lett. 2008, 49, 1601) that the addition of a Pummerer intermediate, generated by exposure of 4 to TFAA, to the terminal alkene 5 and SnCl4 led to efﬁcient C-C bond formation, to give the sulﬁde 6 as a single (unassigned) diastereomer. Pd-catalyzed carbonylation of aryl halides and triflates is a well-established process. Stephen L. Buchwald of MIT has now (J. Am. Chem. Soc. 2008, 130, 2754) extended this transformation to much less expensive tosylates and mesylates such as 7. β-Amino acids have often been prepared from α-amino acids by Arndt-Eistert homologation. Geoffrey W. Coates of Cornell University has devised (Angew. Chem. Int. Ed. 2008, 47, 3979) a more practical alternative, the direct Co-catalyzed carbonylation of an oxazoline 9 to the 2-oxazine-6-one 10. Eiji Shirakawa and Tamio Hayashi of Kyoto University also used (Chem. Lett . 2008, 37, 654) a Co catalyst to promote the coupling of aryl and alkenyl Grignard reagents with enol trifl ates such as 11. Alois Fürstner of the Max-Planck-Institut, Mülheim optimized (Chem. Commun. 2008, 2873) promoters for the Pd-catalyzed Stille-Migata coupling of iodo alkenes such as 14 with alkenyl stannanes such as 15 to give 16. It is particularly noteworthy that their system is fluoride free. The stereocontrolled construction of trisubstituted alkenes continues to be challenging. We described (J. Org. Chem. 2008, 73, 1605) the facile preparation of the diioide 18 from the inexpensive 2-butyn-1,4-diol 17 . Sequential coupling of 18 with an aryl Grignard followed by CH3 Li delivered 19. Brian S. J. Blagg of the University of Kansas established (Tetrahedron Lett . 2008, 49, 141) that Still-Genari homologation of 20 with 21 gave (E)- 22 with high geometric control. Biao Jiang of the Shangahi Institute of Organic Chemistry reported (Organic Lett. 2008, 10, 593) a convenient alternative protocol to give ( Z )-α- bromo unsaturated esters.

Abstract:

During the 1990s, the chemical industry has focused on ways to reduce and prevent pollution caused by chemical synthesis and manufacturing. The goal of this approach is to modify existing reaction conditions and/or to develop new chemistries that do not require the use of toxic reagents or solvents, or that do not produce toxic by-products. The terms “environmentally benign synthesis and processing” and “green chemistry” have been coined to describe this approach where the environmental impact of a process is as important an issue as reaction yield, efficiency, or cost. Most chemical reactions require the use of a solvent that may serve several functions in a reaction: for example, ensuring homogeneity of the reactants, facilitating heat transfer, extraction of a product (or by-product), or product purification via chromatography. However, because the solvent is only indirectly involved in a reaction (i.e., it is not consumed), its disposal becomes an important issue. Thus, one obvious approach to “green chemistry” is to identify alternative solvents that are nontoxic and/or environmentally benign. Supercritical carbon dioxide (sc CO2) has been identified as a solvent that may be a viable alternative to solvents such as CCl4, benzene, and chloroflurocarbons (CFCs), which are either toxic or damaging to the environment. The critical state is achieved when a substance is taken above its critical temperature and pressure (Tc, Pc). Above this point on a phase diagram, the gas and liquid phases become indistinguishable. The physical properties of the supercritical state (e.g., density, viscosity, solubility parameter, etc.) are intermediate between those of a gas and a liquid, and vary considerably as a function of temperature and pressure. The interest in sc CO2 specifically is related to the fact that CO2 is nontoxic and naturally occurring. The critical parameters of CO2 are moderate (Tc = 31 °C, Pc = 74 bar), which means that the supercritical state can be achieved without a disproportionate expenditure of energy. For these two reasons, there is a great deal of interest in sc CO2 as a solvent for chemical reactions. This chapter reviews the literature pertaining to free-radical reactions in sc CO2 solvent.

Abstract:

The European Union is in the process of updating its energy policy and legislative framework under the motto “Clean Energy for All Europeans”. This will facilitate the low carbon energy transition, make it fit for the 21st century, and delivering the EU’s Paris Agreement commitments. Besides expected climate-energy benefits, the EU narrative is introducing new elements to persuade citizens and stakeholders to change their perspective, shifting the general perception from mitigation costs to development opportunities. For example, impact assessment of the new directives estimated that they woul

Abstract:

One potential method for controlling the combustion phasing of a Homogeneous Charge Compression Ignition (HCCI) engine is to vary the fuel chemistry using two fuels with different auto-ignition characteristics. Although a dual-fuel engine concept is technically feasible with current engine management and fuel delivery system technologies, this is not generally seen as a practical solution due to the necessity of supplying and storing two fuels. Onboard partial reforming of a hydrocarbon fuel is seen to be a more attractive way to realize a dual-fuel concept while relying on only one fuel suppl
