Homochiral oligopeptides generated via an asymmetric induction in racemic 2D crystallites at the air-water interface;the system ethyl/thio-ethyl esters of long-chain amphiphilic alpha-amino acids

摘要

N~(epsilon)-stearoyl-lysine-ethyl-ester (C_(18)-OE-Lys) operates as an efficient desymmetrizing agent for the generation of homochiral oligopeptides via a reaction catalyzed by silver ions in two-dimensional (2D) quasi-racemic crystallites of the corresponding thio-ester (C_(18)-TE-Lys) self-assembled on water.
