Abstract
7-Methyl-1-phenyl-5,7-dihydro[1,2]diazepino[5,4-b]carbazol-4(3H)-one representing a new heterocyclic system has been synthesized starting from 2-(9-methyl-9H-carbazol-2-yl)acetic acid, and a new approach has been proposed to the synthesis of 1-R-6-methyl-6H-pyrido[4,3-b]carbazol-3-ols that are close analogs of the natural alkaloid ellipticine.
