该中间体在本合成路线中的序号:(LIII)Synthesis of intermediate (LV): The reaction of epoxide (LI) with 2-bromopropenal diethylacetal (LII) by means of BuLi and CuI gives the adduct (LIII), which is treated with TsOH and acetone yielding the aldehydic acetonide (LIV). Finally, this compound is reduced with NaBH4, chlorinated with N-chlorosuccinimide (NCS) and condensed with Bu3Sn-Li in THF to afford the desired stannane intermediate (LV).
