A stereoselective synthetic method is reported for the molecular framework found in common daucane and isodaucane sesquiterpenoid natural products. The synthetic method constitutes a scalable, modular, and also asymmetric access to a complex natural product scaffold, wherein the substitution pattern and the stereochemistry can be adjusted simply by choosing different starting materials. The method allows
据报道,对于常见的环烷和异环烷倍半萜天然产物中发现的分子骨架,采用立体选择性合成方法。合成方法构成了对复杂的天然产物支架的可扩展,模块化以及不对称的通道,其中可以通过选择不同的起始原料来简单地调节取代模式和立体化学。该方法允许快速引入各种杂环亚结构,例如(苯并呋喃),(苯并)噻吩,二硫辛,噻唑和吲哚,它们实际上也促进并指导了关键的分子内环化步骤。
