to generate functionality with a chiral tertiary/quaternary stereocenter at position C3 of pyrrole. The process proceeds through an amine-catalyzed direct aldol reaction of succinaldehyde with various acceptor carbonyls, followed by a Paal–Knorr reaction with a primary amine in the same pot. A series of chiral C3-hydroxyalkylated N-alkyl/Ar/H-pyrroles have been synthesized for the first time with good
在
吡咯的 C3 位创建具有手性的功能具有挑战性。已经开发了一种操作简单的有机催化方法,以在
吡咯的 C3 位产生具有手性叔/季立体中心的功能。该过程通过
丁二醛与各种受体羰基的胺催化直接羟醛反应进行,然后在同一罐中与
伯胺发生 Paal-Knorr 反应。首次合成了一系列手性C3-羟基烷基化N-烷基/Ar/H-
吡咯,具有良好的收率和高对映选择性。
