描述了一种用于实现真菌次级代谢产物phomoidrides A和B的核心结构的仿生合成的分子内环化策略。环化底物20由二溴化物10分八步制备。用三乙胺在乙腈中处理20导致快速环化,以良好的产率得到21和22。
An intramolecular cyclization strategy for effecting a biomimetic synthesis of the core structure of the fungal secondary metabolites phomoidrides A and B is described. The cyclization substrate20is prepared in eight steps from dibromide10. Treatment of20with triethylamine in acetonitrile results in a rapid cyclization to give21and22in good yield.
