Stereoselective total synthesis of marine secondary metabolite penicitide A has been accomplished for the first time following a convergent approach. The salient feature of this study includes Horner-Wadsworth-Emmons (HWE) olefination, Evans methylations, Crimmins acetate aldol reaction, and cross olefin metathesis. Our synthetic study established the stereochemistry of unassigned C-10 and C-12 centers
收敛性方法首次完成了海洋次生代谢物青霉素A的立体选择性全合成。这项研究的显着特征包括霍纳-沃兹沃思-埃蒙斯(HWE)烯化,埃文斯甲基化,Crimmins醋酸酯羟醛反应和交叉烯烃复分解反应。我们的综合研究建立了未分配的C-10和C-12中心的立体化学,并且还揭示了C-3和C-5立体中心的绝对构型。
