Chiral recognition mechanisms
WebAlthough polysaccharide sorbents have been widely used for chiral separations, the recognition mechanisms have not been fully elucidated. In this study, we focus on one important commercial sorbent, amylose tris[(S)-α-methylbenzylcarbamate] (AS) sorbent.Four solutes containing acyloin, O═C—C—OH, which has a hydroxyl group in the α-position … WebOct 7, 2016 · The chiral recognition mechanism is believed to be based on analyte complexation due to the formation of hydrogen bonds between the protonated amine with oxygen atoms of the macrocycle as summarized earlier [3], [5], [6], [185]. Additional interactions with substituents of the crown ether may contribute to complex formation.
