RESEARCH IN THE CHEMISTRY OF HETEROCYCLIC QUINONE IMINES. 11. EFFECT OF BENZANNELATION ON THE OXIDATIVE CYCLIZATION OF DIARYLAMINO-N-ARYL-1,4-BENZOQUINONE MONOIMINES TO PHENAZINONE DERIVATIVES

2,5-Diarylamino-N-α(β)-naphthyl-1,4-benzoquinone monoimines undergo oxidative cyclization to give benzannelated phenazinone derivatives.The effect of an N-aryl fragment on the ease of cyclization decreases in the order N-β-naphthyl > N-α-naphthyl > N-phenyl. 2-Arylamino-N-phenyl-1,4-naphthoquinone monoimines do not undergo oxidative cyclization to phenazinones.
