Stereoselective synthesis of the pentacyclic key intermediate 22 for (-)-lemonomycin (1) has been accomplished using the Ugi 4-CC reaction with our novel isocyanide 8, a cross-metathesis of 13 and allylsilane and a subsequent intramolecular Hosomi-Sakurai type reaction.
(-)-leomyomycin(1)的五环关键中间体22的立体选择性合成是通过Ugi 4-CC反应与我们的新型异氰化物8、13与烯丙基硅烷的交叉复分解以及随后的分子内Hosomi-Sakurai型反应完成的。
