the nonadjacently linked bis-THF acetogenin bullatanocin (squamostatin C) is described. The synthetic strategy is a modular one based on three components, two mono-THF alkenes and a butenolide precursor, and the olefin cross-metathesis and Wittig olefination as the segment-coupling reactions. The synthesis confirms the structure of the natural product, and its convergent design makes it especially attractive
描述了不相邻连接的双-THF产原素布他那霉素(squamostatin C)的全合成。合成策略是一种基于三种组分,两种单THF烯烃和丁烯内酯前体的模块化策略,并且烯烃的交叉复分解和Wittig烯烃化是链段偶联反应。合成证实了天然产物的结构,其收敛的设计使其特别适合于模拟合成。
