A series of cyclic α- and β-amino esters belonging to a family of indolines and quinolines have been efficiently synthesized to study their behavior in lipase-mediated kinetic resolution reactions. The influence of the fused ring structure to the benzene ring and the position of the ester functionality relative to the amino group have been demonstrated, finding excellent values of enantiodiscrimination
已经有效地合成了属于吲哚啉和喹啉家族的一系列环状α-和β-氨基酯,以研究它们在脂肪酶介导的动力学拆分反应中的行为。已经证明了稠合环结构对苯环的影响以及酯官能度相对于氨基的位置,在念珠菌催化的吲哚-3-羧酸甲酯与正丁醇的酯交换反应中发现了出色的对映异构化值。南极洲观察到脂肪酶B。另一方面,当在烷氧基羰基化,酯交换反应或酯交换反应中使用多种脂酶对吲哚-2-羧酸甲酯或1,2,3,4-四氢喹啉衍生物使用脂肪酶时,发现选择性低至中等。
