Chiral <i>N</i>-Heterocyclic Carbene−Pd(0)-Catalyzed Asymmetric Diamination of Conjugated Dienes and Triene

Abstract

Studies show that a variety of conjugated dienes and triene can be enantioselectively diaminated using di-tert-butyldiaziridinone as nitrogen source and chiral N-heterocyclic carbene-Pd(0) complex as catalyst in good enantioselectivity (62-91% ee) with high regio- and diastereoselectivity.
