(+)-Goniodiol, its acetates and β-trifluoromethyl derivative, (+)-7-epi-Goniodiol and (+)-9-deoxygoniopypyrone, the representatives of styryllactones have been synthesized in a short and general way. The key steps involve the regioselective asymmetric dihydroxylation and the palladium-catalyzed cross-coupling of cyclic allylic carbonate with vinyltributylstannane.
