Abstract

Abstract The pentacyclic skeleton 10 of the aspidospermine group of indole alkaloids has been constructed from hexahydrocarbazol-4-one 2 with high stereoselectivity. The synthesis of (±) 19-oxo aspidofractinine 12, a direct precursor of aspidofractinine 4, illustrates the usefulness of this new general strategy.
