In this report, the originally proposed rupestonic acid (5) and pechueloic acid (3) were efficiently synthesized. The chiral lactone 13, recycled from the degradation of saponin glycosides, was utilized to prepare the key chiral fragment 11. During the exploration of this convergent assembly strategy, the ring-closing metathesis (RCM), SmI2-prompted intermolecular addition, and [2,3]-Wittig rearrangement
在该报告中,有效地合成了最初提出的鼠李酮酸(5)和油酸(3)。从皂苷苷的降解中回收的手性内酯13被用于制备关键的手性片段11。在探索这种聚合组装策略的过程中,闭环复分解(RCM),SmI 2提示分子间加成和[2,3] -Wittig重排被证明是合成亚基的有效方法。
