Abstract

The various mechanisms involved in the highly enantioselective, iridium-catalyzed monoallylations of ammonia are explained. The methodology is shown to be extremely useful for the one-pot syntheses of heterodiallylamines and allylic amides.

Abstract

A study of the relationship between the stereochemical elements of a phosphoramidite ligand and the stereoselectivity of enentioselective iridium-catalyzed amination of allylic carbonates is reported. During catalyst activation, a complex of a phosphoramidite ligand possessing one axial chiral binaphtholate group and two resolved phenethyl substituents converts to a more reactive cyclometalated complex containing one distal chiral substituent at nitrogen.
