A convenient route for the synthesis of triazole fused benzoxazepines or benzodiazepines in aqueous micellar medium has been described. The two step one-pot synthesis involves Sonogashira reaction of prop-2-ynyl 2-azidobenzoates and aryl iodides followed by intramolecular azide–alkyne cyclization using Pd(CH3CN)2Cl2 as catalyst and ethanedial,1,2-bis(2-methyl-2-phenylhydrazone) as ligand, under atmospheric
已经描述了在水性胶束介质中合成三唑稠合的苯并x氮杂或苯并二氮杂的便利途径。两步一锅法合成涉及2-丙二炔丙基丙炔基-2-碘基苯甲酸和芳基碘化物的Sonogashira反应,然后使用Pd(CH 3 CN)2 Cl 2作为催化剂和乙二醛1,2,bis( (2-甲基-2-苯基hydr)作为配体,在大气条件下。该方法不使用铜盐作为催化剂以及有害的有机溶剂。
