PENTACYCLIC INDOLE ALKALOIDS: A SHORT SYNTHESIS OF (+/-)-N(a)-BENZYL-20-DESETHYLASPIDOSPERMIDINE

The synthesis of (+/-)-N(a)-benzyl-20-desethylaspidospermidine in 8 steps and 25percent overall yield from cyclohexanedione is described.

A Novel and Efficient Synthesis of the Aspidosperma Alkaloid Ring System: N(a)-Benzyldeethylaspidospermidine

Nonoxidative photocyclization of the aryl enaminone 3 led to the formation of the hexahydrocarbazol-4-one 4.Alkylation of the anion derived from 4 with iodoacetamide and dehydration gave the tetracyclic enamide 9, which was reduced to the imine 10 with Li
