Enantioselective transfer aminoallylation: synthesis of optically active homoallylic primary amines.

A camphorquinone-derived chiral homoallylic amine was found to react with various aldehydes via imine formation and asymmetric 2-azonia-Cope rearrangement to give optically active homoallylic primary amines. A practical level of enantioselectivity with high functional group tolerance has been attained in this transformation.
