New simple primary amine-thiourea organocatalysts and their application in asymmetric conjugate addition

摘要

A kind of simple primary amine thiourea organocatalysts was developed. And their application in asymmetric conjugate addition of ketone to nitroalkene was investigated. In the presence of the new primary amine-thiourea, the conjugate addition of ketone to nitroalkene proceeded smoothly to afford the 1,4-adducts in high yields with good enantioselectivities. (
