The asymmetric total synthesis of four diastereomers of laingolide A was achieved, which led to the unambiguous assignment of the stereochemistry of the natural product. The salient features of the convergent, fully stereocontrolled approach were a copper-catalysed stereospecific Kumada-type coupling, a Julia-Kocienski olefination and an RCM/alkene migration sequence to access the desired macrocyclic
实现了Laingolide A的四个非对映异构体的不对称全合成,这导致了天然产物的立体化学的明确分配。收敛的,完全立体控制的方法的显着特征是铜催化的立体有特异性的Kumada型偶联,Julia-Kocienski烯烃化反应和RCM /烯烃迁移序列以访问所需的大环烯酰胺。
