(+)-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.
(+)-Goniodiol 及其醋酸盐和δ-三氟甲基衍生物、(+)-7-epi-Goniodiol 和 (+)-9-deoxygoniopypyrone 是苯乙烯内酯的代表,这些化合物已通过简短而通用的方法合成。关键步骤包括环状烯丙基碳酸酯与乙烯基三丁基锡的区域选择性不对称二羟基化和钯催化交叉耦合。
