A total synthesis of the bis-deoxylophotoxin 25a, the probable biological precursor to the neurotoxin lophotoxin 1 is described. The synthesis uses a strategy based on sequential carbanion alkylation and Stille coupling between the chiral building blocks 5 and 6, leading to the furanocembranolide 23, following by functional group manipulation.
本文描述了双脱氧洛福毒素25a的总合成,这可能是神经毒素洛福毒素1的
生物前体。该合成采用了基于顺序卡贝离子烷基化和斯蒂尔偶联的策略,使用了手性构建块5和6,最终合成了
呋喃海葵内酯23,并进行功能团的改造。
