o-Phenylenediamine as a Source of Fused Azole, Azine, and Diazepine Derivatives

Abstract: A facile synthetic approach to diazepine and/or benzimidazole derivatives has been developed through the reaction of enamine [N1-(1-phenylethenyl)benzene-1,2-diamine] obtained from o-phenylenediamine and acetophenone. Its reaction with isophthaloyl chloride produced bis(1,5-benzodiazepinyl)benzene derivative via cyclization involving the nucleophilic enamino carbon atom, whereas the cyclocondensation with diethyl succinate occurred at the nucleophilic nitrogen atom to give bis-benzimidazole derivative. Depending on the conditions, the cyclization with carbon disulfide in DMSO afforded tricyclic 4-phenylimidazo[4,5,1-hi]indole-2(1H)-thione, while 4-phenyl-1,3-dihydro-2H-1,5-benzodiazepine-2-thione was formed in the presence of pyridine. Cyclocondensation of o-phenylenediamine with two equivalents of acetophenone in acid medium produced 3-phenyl-1-(1-phenylethenyl)-1,4-dihydroquinoxaline. N-(2-Aminophenyl)thiourea obtained from o-phenylenediamine and ammonium thiocyanate reacted with chloroacetyl chloride, diethyl malonate, carbon disulfide, and sodium nitrite in aqueous HCl to afford benzimidazole, thiadiazolobenzimidazole, and benzotriazole derivatives.
