An asymmetric biomimetic transamination of aromatic ketones to opticallyactive amines with o-HOPhCH2NH2 as amine source catalyzed by hydroquinine-derived chiral base is described. Up to 85% ee was obtained.
A highly enantioselective intermolecular benzylic C(sp3)−H bond amination by using a chiral cationic copper catalyst and oxidant di-tert-butyl peroxide is reported. This mild, straightforward method can be used to transform an array of feedstock alkylarenes and amides into chiral amines with high enantioselectivities, and it has good functional group tolerance and a broad substrate scope.
