A newly developed chiral imidazole nucleophilic catalyst, Acyloxy-DPI, was readily prepared and successfully applied to the enantioselective Black rearrangement with up to 88% ee for a wide range of substrates possessing different substituted groups. A plausible mechanism for the high enantioselectivity was proposed.
