enzyme-catalyzed asymmetric domino aza-Michael/aldol reaction of 2-aminobenzaldehyde and α,β-unsaturated aldehydes is achieved. Pepsin from porcine gastric mucosa provided mild and efficient access to diverse substituted 1,2-dihydroquinolines in yields of 38%–97% with 6%–24% enantiomeric excess (ee). This work not only provides a novel method for the synthesis of dihydroquinoline derivatives, but also promotes
摘要实现了前所未有的酶催化2-氨基苯甲醛与α,β-不饱和醛的不对称多米诺氮杂-迈克尔/醛醇缩合反应。来自猪胃粘膜的胃蛋白酶可轻而有效地获得各种取代的1,2-二氢喹啉,其对映体过量(ee)的产率为38%至97%,而对映体过量为6%至24%。这项工作不仅为合成二氢喹啉衍生物提供了一种新颖的方法,而且还促进了酶催化滥交的发展。
