Synthesis of N-Arylquinone Diimine Derivatives of 2H-Benzimidazo[2,1-e]acridine and Their Reactions with Aromatic Amines

Abstract

Oxidative coupling of 6,7,8,9,9a,10,11,12,13,14-decahydro-5H-benzimidazo[2,1-e]acridine with reagents containing a primary aromatic amino group forms p-quinone diimines of the 2H-benzimidazo[2,1-e]-acridine series. The subsequent acid-activated 1,4-nucleophilic addition reaction of the products with the same reagents followed by autooxidation gives rise to 3-arylamino-substituted quinone diimines of the specified series.
