摘要

摘要为对映选择性合成(-)-反式和(+)-反式后位化合物以及(-)-(6Z,9Z,4S,5S)-反式4,5-环氧壬二烯这两种重要的天然反式环氧信息素，开发了一种简洁、灵活、高效的有机催化策略。该方法的关键转化包括有机催化的不对称Jørgensen环氧化和立体选择性(Z)-Wittig烯烃。值得注意的是，Jørgensen环氧化步骤确保了目标信息素对映体的合成具有优异的对映纯度（高达97% ee）。

Concise organocatalyzed epoxidation based total synthesis of (−)- and (+)-trans-posticlures and (−)-(6Z,9Z,4S,5S)-trans-4,5-epoxynonadeca-6,9-diene†

A concise, flexible and efficient organocatalytic strategy has been developed for the enantioselective synthesis of (−)-trans- and (+)-trans-posticlures, along with (−)-(6Z,9Z,4S,5S)-trans-4,5-epoxynonadeca-6,9-diene which are remarkable natural trans-epoxide pheromones. The key transformations in this approach involve an organocatalyzed asymmetric Jørgensen epoxidation and stereoselective (Z)-Wittig olefination. Notably, the Jørgensen epoxidation step ensures excellent enantiopurity (up to 97% ee) in the synthesis of the target pheromone antipodes.
