[reaction: see text] An enantioselective total synthesis of (-)-stemonine (1) is reported via a convergent assembly of the acyclic precursor 2. Key transformations include a Staudinger-aza-Wittig reaction to form the central perhydroazepine ring system and an iodine-induced tandem cyclization to construct the pyrrolidino-butyrolactone framework.
[反应:见正文]通过无环前体2的会聚组装,报道了对-(-)-stemonine(1)的对映选择性全合成。关键的转化包括Staudinger-aza-Wittig反应形成中央全氢氮杂多环体系和碘诱导的串联环化反应,以构建吡咯烷基-丁内酯框架。
