Highly enantioselective allylic amination reaction through aerobic oxidative organo-organo dual catalytic system

A variety of enantioenriched substituted imides were facilely synthesized through aerobic oxidation/allylic amination reactions of aldimines with MBH carbonates under N-heterocyclic carbene (NHC)/chiral tertiary amine dual catalysis. The strategy is attractive and valuable because of the convenient one-step procedure, environmental friendliness, high enantioselectivity and good functional-group tolerance. An NHC/chiral tertiary amine dual catalytic system for the aerobic oxidation/allylic amination reaction has been developed. The combination of NHC with organo-catalysts especially with tertiary amine catalysts remains an underexplored area.
