Abstract

The synthesis of N(b)-benzyl-2-(dimethyl 2-malonyl)- and 2-(methyl 2-acetyl)tryptamines (21, 25) provides access to methyl ,4,5,6-hexahydroazepino[4,5-b]indole-5-carboxylate (12) and methyl hexahydro-1H-pyrrolo[2,3-d]carbazole-6-carboxylate (9), potential intermediates for the syntheses of strychnos alkaloids. A new condensation-sigmatropic rearrangement reaction gives the tetracyclic product 9 directly from the tryptamine 25.
