A simple, efficient, and general method has been developed for the synthesis of various 4-substituted 2-amino-6,6-diphenyl-8-aryl-6,8-dihydroimidazo[1,2-a] [1,3,5] triazine-7(4-H)ones . This involved condensation of 1-(5-oxo-4,4-diphenyl-1-aryl-4,5-dihydro-1H-imidazol-2-yl)guanidines 2a and 2b, themselves obtained from the reaction of aryl biguanides 1a/b with benzil, with the requisite carbonyl compounds
已开发出一种简单,有效且通用的方法,用于合成各种4-取代的2-氨基-6,6-二苯基-8-芳基-6,8-二氢咪唑基[1,2- a ] [1,3, 5]三嗪-7(4- H)酮。这涉及1-(5-氧代-4,4-二苯基-1-芳基-4,5-二氢-1 H-咪唑-2-基)胍2a和2b的缩合,它们本身是从芳基双胍1a的反应获得的/ b与苯偶酰,以必要的羰基化合物。这两个步骤都是在密封容器中使用微波加热进行的。J.杂环化学。(2010)。
