Total Synthesis of (−)-Stemonine WilliamsDavid R. ShamimKhalida ReddyJayachandra P. AmatoGeorge S. ShawStephen M. 2003 An enantioselective total synthesis of (−)-stemonine (<b>1</b>) is reported via a convergent assembly of the acyclic precursor <b>2</b>. 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.
