A total synthesis of camptothecin has been carried out. Central to our synthesis is the intramolecular condensation of a suitably designed ketol, which in turn was obtained from a tricyclic ABC ring synthon. A tandem reductive amination and Michael addition sequence on an unsaturated quinoline ester was employed for the assembly of the ABC skeleton.
已经进行了喜树碱的全合成。合成的核心是适当设计的酮醇的分子内缩合,而酮醇又是从三环ABC环合成子获得的。在不饱和喹啉酯上的串联还原胺化和迈克尔加成序列被用于ABC骨架的组装。
