thiol estercarbonyl sulfidearyllithiumcuprateregioselectivityA simple and efficient procedure for the synthesis of thiol esters 3 has been developed by utilizing carbonyl sulfide (S=C=O, 1) as a thiocarboxylation agent. Treatment of 1 with organolithium reagents at78 掳C for 5 min yielded lithium...
Biocidal polymers: Synthesis, antimicrobial activity, and possible toxicity of poly (hydroxystyrene‐co‐methylmethacrylate) derivatives Functionalized polymers have gained much interest in the last decades. This is due to their functional group and their polymer nature that give them unique... ER Kenawy...
Here we present a practical and general synthesis of tertiary alkylamines through the addition of alkyl radicals to all-alkyl-iminium ions. The process is facilitated by visible light and a silane reducing agent, which trigger a distinct radical initiation step to establish a chain process. This ...
Carbonyl-carbonyln→π*interactions where a lone pair (n) of the oxygen atom of a carbonyl group is delocalized over theπ* orbital of a nearby carbonyl group have attracted a lot of attention in recent years due to their ability to affect the 3D structure of small molecules, polyesters, p...

SYNTHESIS OF [1-(ETHYL "ESTER OF CARBONYLGLYCINE), 2-D-ARGININE, 5-VALINE]ANGIOTENSIN II AND [1-CARBON- YLGLYCINAMIDE, 2-D-ARGININE, 5-VALINE]ANGIOTENSIN II R. I~. Vegner, G. I. Chipens, UDC 547.964.4+577.17.07 and V. K. Kibirev As the result of an analysis of the ...
Presently available data allow us to make suggestions with regard to the active centres for various reactions of syngas. It seems that for methanol and higher alcohol synthesis an active centre always requires the presence of a promoter within close proximity. In contrast to this, formation of hyd...
[2+3] cycloaddition of carbonyl ylide with C=O bond has been used by Hodgson and co-workers in their study toward the synthesis of zaragozic acid as shown inScheme 11.30Recently, a three-component reaction approach tosyn-α-hydroxy-β-amino ester based on the trapping of the carbonyl ylide...
