The development of an efficient synthetic method enabled multi-gram synthesis of a key intermediate, which is useful for the modification at the C6-functional group of galbonolide analogues. The structure of a key intermediate including a conjugated diene was afforded by Horner-Emmons reaction, alkylation of Weinreb amide with alkyl lithium and a subsequent Wittig reaction.
有效合成方法的发展实现了关键中间体的多克合成,这对于加蓬内酯类似物的C6官能团的修饰非常有用。通过霍纳-埃蒙斯反应,Weinreb酰胺与烷基锂的烷基化以及随后的Wittig反应提供了包括共轭二烯的关键中间体的结构。
