A convergent route for the asymmetric total synthesis of antibacterial macrolide sorangiolide A has been developed for the first time. The key feature of this synthesis includes Krische iridium-catalyzed anti-diastereoselective carbonyl crotylation, Crimmins acetate aldol, Yamaguchi esterification, Julia–Kocienski olefination, Horner–Wadsworth–Emmons olefination, and ring-closing metathesis. The origin
首次开发了抗菌大环内酯类索乔奥内酯 A 的不对称全合成的收敛途径。这种合成的主要特征包括 Krische 铱催化的抗非对映选择性羰基碳化反应、Crimmins 乙酸醛、Yamaguchi 酯化反应、Julia-Kocienski 烯烃反应、Horner-Wadsworth-Emmons 烯烃化和闭环复分解。已经研究了天然产物 C1 和 C2 中心的 13C1H} NMR 信号低强度的来源,揭示了天然产物在溶液相中可能存在的形式。
