Abstract: Formal total syntheses of the pyrrolidine alkaloids (-)-codonopsine and (-)-codonopsinine, as well as the synthesis of a new C-aryl azasugar were accomplished from a common 5-membered, enantiomerically pure endocyclic enecarbamate. The key step in those syntheses relies on a novel and practical version of the Heck reaction involving endocyclic enecarbamates and diazonium salts. (C) 1999 Elsevier Science Ltd.
