unexpected structural incongruity between coleophomones 1 and the reported structure of recently isolated natural product 2 was confirmed by total synthesis of key semi-synthetic derivative 3 and its positional isomer 4. In addition, possible mechanisms for the interconversion of expected structure 22 to observed compound 2 are postulated, some of which may have an important role in the biosynthetic origin
通过关键半合成衍生物3及其位置异构体4的全合成,证实了骨磷蛋白1与最近分离出的天然产物2的报道结构之间意外的结构不一致。此外,假定可能的结构将预期结构22相互转化为观察到的化合物2,其中某些可能在这些结构独特的天然产物的生物合成来源和化学中起重要作用。
