Resumen
Abstract Alkylation is one of the most ubiquitous forms of DNA lesions. However, the motif preferences and substrates for the activity of the major types of alkylating agents defined by their nucleophilic substitution reactions (SN1 and SN2) are still unclear. Utilizing yeast strains engineered for large-scale production of single-stranded DNA (ssDNA), we probed the substrate specificity, mutation spectra and signatures associated with DNA alkylating agents. We determined that SN1-type agents preferably mutagenize double-stranded DNA (dsDNA), and the mutation signature characteristic of the ac

Resumen
Hydrazine and azapeptide analogs were synthesized effectively by alkylation of alkylidene carbazates and semicarbazones. In comparisons of benzylidene, benzhydrylidene, and fluorenylidene tert-butyl carbazates in alkylations using bases of different pKb character, superior conversion was obtained using the fluorenone derivative. Mild alkylation conditions were found employing Et4NOH as base and used to convert fluorenylidene tert-butyl carbazate into 13 different protected hydrazines. Moreover, racemization was avoided during alkylation of fluorenylidene semicarbazide in the synthesis of aza-p

Resumen
Alkylating ability of oxetane ring in carbohydrate structure was investigated and flexible method for bolaform amphiplile skeleton construction with xylose as polar heads is proposed. The method is based on oxetane ring opening in easily accessible 3,5-anhydro-1,2-O-cyclohexylidenexylofuranose (1). One step nitrogen alkylation in terminal diamines with 1 gave basic cationic bolaform skeleton with xylose as potential polar heads and deliberately chosen length of non polar spacer.

Resumen
Alkylation of the (R)-camphor imine of tert-butyl glycinate with a variety of alkylating agents gave diastereoselectivities ranging from 0–100%. Simple alkyl halides larger than methyl give de's (diastereomeric excesses) of ca. 50% whereas those derived from allylic type systems afford de's of 75–100%. The results are best explained by invoking a transition state interaction between the π system of the alkylating agent and the imine which, for steric reasons, requires alkylation to occur from the pro-R face.

Resumen
Recently, a number of papers have emerged demonstrating copper-catalyzed alkylation reactions of electron-rich small molecules. The processes are generally thought to be related to long established atom-transfer radical reactions. However, unlike classical reactions, these new transformations lead to simple alkylation products. This short review will highlight recent advances in alkylations of nitronate anions, alkenes and alkynes, as well as discuss current mechanistic understanding of these novel reactions.

Abstract Synthesis and spectroscopic analysis of some alkylated DNA purine bases are described.

Resumen
Thieno[2,3-d]pyrimidines are an important class of heterocyclic compounds with a wide range of biological activities. The thieno[2,3-d]pyrimidin-4-one system is of the greatest interest to scientists, as it is one of a large number of possible thienopyrimidine derivatives. The presence of an amide fragment in these molecules allows for the introduction of various substituents via alkylation reactions. On the other hand, the presence of N- and O-nucleophilic centres makes it possible to form different types of alkylation products.

Abstract Base damage and topoisomerase I (Top1)-linked DNA breaks are abundant forms of endogenous DNA breakage, contributing to hereditary ataxia and underlying the cytotoxicity of a wide range of anti-cancer agents. Despite their frequency, the overlapping mechanisms that repair these forms of DNA breakage are largely unknown. Here, we report that depletion of Tyrosyl DNA phosphodiesterase 1 (TDP1) sensitizes human cells to alkylation damage and the additional depletion of apurinic/apyrimidinic endonuclease I (APE1) confers hypersensitivity above that observed for TDP1 or APE1 depletion alon

Abstract A cobalt–N-heterocyclic carbene catalyst allows ortho-alkylation of aromatic imines with unactivated primary and secondary alkyl chlorides and bromides under room-temperature conditions. The scope of the reaction encompasses or complements that of cobalt-catalyzed ortho-alkylation reactions with olefins as alkylating agents that we developed previously. Stereochemical outcomes of secondary alkylation reactions suggest that the reaction involves single-electron transfer from a cobalt species to the alkyl halide to generate the corresponding alkyl radical.

In addition, a limited study has also been carried out into the sulfurisation of alkylphenols. Both the alkylsalicylic acids and the sulfurised aJkylphenols are used as oil additives.

A novel camphor-derived hydroxy ketal 138 has been developed as a crural auxiliary, and used to prepare a series of six carboxylic esters of increasing steric bulk. The α-benzylation of this series of esters was achieved with diastereoselectivities of 59 - 83％ d. e. and in 39 - 48％ material yield. These results compared very favourably with those obtained in earlier studies using a regioisomeric analogue as the chiral auxiliary.

Resumen
Alkylation is the transfer of an alkyl group (CnH2n+1) from one molecule (alkylating agent) to another where it can attach typically to carbon (C-alkylation), but also to oxygen (O-alkylation), nitrogen (N-alkylation), sulfur (S-alkylation) and phosphorous (P-alkylation) depending on the reaction conditions. This chapter discusses the importance of alkylation reactions, then looks at green improvements made by using solid acid catalysts, ionic liquids in Friedel–Crafts reactions, the atom economic borrowing hydrogen strategy and directed alkylation of C–H bonds using alkenes.

Resumen
Abstract Materials selection in HF-alkylation units is mostly based on long time experience. The most widely used material in the alkylation units is standard carbon steel, because it is capable to form a thick protective FeF2 layer in concentrated or anhydrous hydrofluoric acid. The corrosion resistance decreases, when the acid is dilute (less than 64% HF) or the temperature is above 160 °F (70 °C). The composition and metallurgical state are also suspected to affect the corrosion resistance of carbon steel. The effect of composition appears more complicated than believed, especially the A-10

Online non-intrusive automated corrosion monitoring of HF alkylation units is valuable due to the safety risks associ

Resumen
Abstract Sulfuric acid alkylation (SAA), the conversion of olefins and butane to high-octane alkylate using highly concentrated sulfuric acid as a catalyst, is a very profitable refinery operation with powerful incentives to maximize throughput. However, until recently there were only minimal corrosion data available upon which to assess the possible equipment damage resulting from changes in SAA unit operating conditions. Thus, a joint industry program (JIP) entitled “Prediction of Corrosion in Sulfuric Acid Alkylation Units” was launched in January 2006 and completed in January 2010, to deve

Resumen
Abstract The T-8-20 Task Group conducted a survey of plant practices and of the performance of materials of construction in HF Alkylation Units. A primary goal of the survey was to expand the limited body of information on alternative alloy performance in HF alkylation units and to better define the susceptibility of steel to hydrogen induced cracking. Survey results indicate that although the incidence of cracking is reported to be low, hydrogen blistering is commonly found in pressure vessels. Few applications of alternative alloys were reported, but several areas of vulnerability or high co
