hydrosilane [(EtO)3SiH] was revealed in the one-carbon migration and isomerization of 4,4-biaryl-substituted 1-butenes, in which the (EtO)3SiH plays a key role in the palladium-catalyzed one-carbon migration and subsequent isomerization of terminal alkenes. This catalytic protocol is applied in the synthesis of a key building block of cassumunin C in high yield and promising selectivity.
由 PdCl2(PPh3)2 和氢硅烷 [(EtO)3SiH] 生成的原位形成钯催化剂体系的催化活性体现在 4,4-联芳基取代的 1-丁烯的单碳迁移和异构化中,其中(EtO)3SiH 在钯催化的单碳迁移和随后的末端烯烃异构化中起关键作用。该催化方案用于以高产率和有希望的选择性合成 cassumunin C 的关键构建块。
