摘要

Abstract Aldolases are enzymes that catalyze stereospecific aldol reactions in a reversible manner. Naturally occurring aldolases include class I aldolases, which catalyze aldol reactions via enamine intermediates, and class II aldolases, in which Zn 2+ enolates of substrates react with acceptor aldehydes. In this work, Zn 2+ complexes of L-prolyl-pendant [15] aneN 5 (ZnL 3), L-prolyl-pendant [12] aneN 4 (ZnL 4), and L-valyl-pendant [12] aneN ...
