  Total Synthesis of (−)-Senepodine G and (−)-Cermizine C

  摘要：

  An efficient, stereospecific synthesis of the alkaloids senepodine G (2 and cermizine C (1) has been completed using the BF3 center dot Et2O-promoted stereospecific addition of Me2CuLi to alpha,beta-unsaturated lactam 6 to provide lactam 3 the addition of MeMgBr followed by HCl to convert 3 to senepodine G (2) (six steps, 40% overall yield), and the stereospecific NaBH4 reduction of 2 to give cermizine C (1) (seven steps, 40% overall yield).

  nonracemic Betti base as a chiral auxiliary. The key step is that the auxiliary residue was removed by a novel base-catalyzed N-debenzylation via a formation of o-quinone methide mechanism in stead of the traditional hydrogenolysis, by which the alkene or alkyne groups survived. By this method, ten 2-alkene- or 2-alkyne-containing chain substituted piperidines were prepared on the gram scale within

  通过使用非外消旋的Betti碱作为手性助剂，建立了制备对映体纯的含2个烯烃或2个炔烃的链取代哌啶的一般方法。关键步骤是代替传统的氢解反应，通过传统的氢解反应，通过邻甲基苯甲酸甲酯的形成，通过新颖的碱催化的N-脱苄基反应去除了辅助残基。通过这种方法，在数小时内以克为单位制备了十个含2-烯烃或2-炔烃的链取代的哌啶。为了证明该方法的有效性和产品的多功能性，使用（S）-2-烯丙基完成了天然生物碱（+）-peltierine，（-）-lasubine II和（+）-cermizine C的总合成--N -Boc-哌啶为通用成分。

  The synthesis of the title compound, a key intermediate in the synthesis of some lycopodium and lupin alkaloids, is reported. From a stereochemical standpoint the key steps are the stereoselective cyclocondensation of ketodiester 1 with (R)-phenylglycinol and the stereocontrolled reduction, with retention of configuration, of the oxazolidine ring in the resulting oxazolopiperidone lactam 2.
