Abstract

A new entry into the 1,6-diazaphenalene ring system via carbonylation of the anion derived from 4-methyl-5-amino-6-methoxyquinoline 6 is described. This method permits the preparation of 1,6-diazaphenalene derivatives not easily accessible through substitution reactions on the parent heterocycle.
