Chiral N-heterocyclic carbene-Pd(0)-catalyzed asymmetric diamination of conjugated dienes and triene

[GRAPHICS] 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 enantio selectivity (62-91% ee) with high regio- and diastereoselectivity.
