摘要

Abstract: The substituted dehydroindolizidine 8 has been prepared from the exocyclic vinylogous urethane 4 via an acylative ring closure. The specific formation of the enolate required for further elaboration to Elaeocarpus alkaloid precursors has been achieved by making use of the vinylogous amide I $ _
