Dynamic kinetic asymmetric allylation of hydrazines and hydroxylamines

Org Lett. 2009 Aug 6;11(15):3258-60. doi: 10.1021/ol901185d.

Abstract

Hydrazines and hydroxylamines have been found to be excellent nucleophiles for the palladium-catalyzed dynamic asymmetric allylic amination of vinyl epoxide, with good yields and enantioselectivities of up to 97% ee. This method is applicable to acyclic and heterocyclic amines and was applied toward a five-step synthesis of (R)-piperazic acid.
