白介素6的强效和选择性的抑制剂(+)-麦迪多林A(1)和B(2)的短而有效的全合成已经实现。该合成的特点是关键的螯合控制的1,4-非对映选择性酰化反应生成季碳,以及烯丙基硅烷的分子内酰化反应建立环戊烯单元。
A short and efficient total synthesis of (+)-madindolines A (1) and B (2), potent and selective inhibitors of interleukin 6, has been achieved. The synthesis features a key chelation-controlled 1,4-diastereoselective acylation to generate the quaternary carbon and an intramolecular acylation of allylsilane to build up the cyclopentene unit.
