Synthesis of novel pyrido[3,4‐<i>f</i>]pyrrolo[1,2‐<i>b</i>][1,2,5]triazepines. A Novel heterocyclic ring system

Abstract

Abstract The synthesis of novel pyrido[3,4‐ f ]pyrrolo[1,2‐ b ][1,2,5]triazepines 6–17 is described. Subsequent reactions on the parent system include reduction, Grignard addition, alkylation, acylation and carbamoylation.
