asymmetric synthesis of penaresidin A is disclosed. A β-protected amino-γ,δ-unsaturated sulfoxide was prepared by stereoselective addition of the lithio anion of (R)-methyl p-tolyl sulfoxide to an unsaturated sulfinylimine. The pendant sulfoxide group was used as an intramolecular nucleophile to functionalize an alkene regio- and stereoselectively to furnish a bromohydrin, which was employed as the key intermediate
