摘要:

开发了两种结构简单的反式-4-羟基-L-脯氨酰胺有机小分子催化剂,用于高效催化不对称迈克尔加成反应。在醛和硝基烯的不对称迈克尔加成反应中,以(S)-1,1'-联-2-萘酚为协同催化剂,对两种脯氨酰胺衍生物的催化活性进行研究,发现催化剂摩尔分数仅为0.5%~1%时,产物的收率最高可达96%,非对映和对映选择性值最高可达99/1和99%。该方法为开发低成本、高效率的不对称迈克尔加成反应有机催化剂体系提供了简单易行的选择。

Abstract:

The structurally simplified trans-4-hydroxy-L-prolinamide derivatives are prepared as the efficient organocatalysts for Michael-type asymmetric reactions. Their catalytic behaviors are evaluated in the asymmetric Michael addition of aldehydes to nitroolefins with (S)-1,1'-bi-2-naphthol as the co-catalyst. Excellent diastereo-and enantioselectivities(respectively up to >99/1 and 99%), as well as high yields(up to 96%)are achieved even at the catalyst loading of as low as 0.5%~1%(molar percent). This study provides a facile method to develop the low-cost and highly efficient organocatalyst system for the asymmetric Michael addition reactions.

Key words: Asymmetric catalysis, 4-Hydroxy-L-prolinamide, S)-1, 1'-Bi-2-naphthol, Michael addition
