culminated in the first asymmetric total synthesis of the Aspidosperma alkaloid limaspermidine is described. The successful enantioselective route to (−)-limaspermidine proceeds in 10 steps and with the isolation of only six intermediates using a Pd-catalyzed enantioselective decarboxylative allylation we have recently developed. This first enantioselective synthesis of (−)-limaspermidine establishes
描述了合成策略的演变,该策略最终导致了Asperdosperma生物碱Limaspermidine的首次不对称全合成。我们最近开发了成功的对(-)-利马斯idine定的对映选择性路线,该路线分10个步骤进行,仅使用Pd催化的对映选择性脱羧烯丙基化仅分离六个中间体即可。(-)-利马培啶的该第一对映选择性合成明确地建立了其绝对构型,并允许Aspidoalbine生物碱(-)-1-乙酰基aspidobidine的第一不对称形式的全合成。
