The first diastereoselective construction of butane-type and butyrolactone-type secocyclolignanes was achieved by the application of a high-valency heterobimetallic Ir–Sn complex to benzyl alcohols prepared from an Evans’s anti-aldol product. The elimination of an acetoxymethyl group to give a cinnamyl structure by using a high-valency heterobimetallic Ir–Sn complex was also observed in this study.
