Two novel styryllactones, 7-epi-goniodiol and leiocarpin A, isolatedfrom Goniothalamus leiocarpus, were stereoselectively synthesized in a short and efficient route from cinnamyl alcohol based on the asymmetric epoxidation and the palladium-catalyzed cross-coupling of vinyl epoxide with vinyltributylstannane.

(+)-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.
