The kinetics of aminolysis of 1-thio-β-D-glucopyranosyl esters of N-protected alanines (1) in dichloromethane, at 26°, by ethyl glycinate, under pseudo-first-order conditions follows the relationship k-obsd = k2[H-Gly-OEt]. Significant differences were observed in the rates of dipeptide forming aminolysis for 1-thiolesters 1a-1f, depending on N-acyl substituents and the configuration of alanine.
在伪一级反应条件下,甘氨酸乙酯在26°下由N-保护的丙氨酸(1)在二氯甲烷中的1-硫代-β-D-吡喃葡萄糖基酯的氨解动力学动力学关系为k- obsd = k 2 [H-Gly-OEt]。根据N-酰基取代基和丙氨酸的构型,观察到1-巯基1a-1f的二肽形成氨解反应的速率存在显着差异。
