A remarkable substituent effect by a trimethylsilyl group was observed on the enantioselectivity of the tandem asymmetric epoxidation and enantiospecific ring expansion of 2-cyclopropylidene-2-(4,5-dimethoxy-2-(trimethylsilyl)phenyl)ethanol (24), affordin

By extending our oxidative phenol-coupling reactions using a hypervalent iodine(III) reagent, a versatile synthetic procedure for the galanthamine-type Amaryllidaceae alkaloids was accomplished. The first total synthesis of (±)-sanguinine and the total syntheses of (±)-galanthamine, (±)- narwedine, (±)-lycoramine, and (±)-norgalanthamine were also successfully carried out.
