[反应:已经实现了(+)-madindolines A(1)和B(2)(白细胞介素6的有效和选择性抑制剂)的短而有效的全合成。合成的特点是一个关键的螯合控制的1,4-非对映选择性酰化反应,以产生季碳和烯丙基硅烷的分子内酰化,以建立环戊烯单元。
[reaction: see text] 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.
