Formal synthesis of (+)-isolaurepinnacin

The stereoselective formal synthesis of (+)-isolaurepinnacin is described. The required key oxepene skeleton possessing cis-oriented alkyl substituents at the α,ω-positions was stereoselectively constructed via the cyclization of the corresponding hydroxy epoxide promoted by the (Bu3Sn)2O/Zn(OTf)2 system.
