通过芳族醛,巴比妥酸/硫代巴比妥酸和1的一锅三组分缩合反应,开发了一种高效的P 2 O 5介导的吡啶基[2,3-d:6,5-d]双嘧啶合成方法。乙醇中的3-3-二甲基-6-氨基尿嘧啶。筛选了所有合成产物的体外抗结核活性,结果表明,大多数化合物对结核分枝杆菌H 37 R V菌株均表现出中等至良好的活性。
Some fused heterocyclic pyrimidines have been synthesized in high yields using ultrasound irradiation in a one-pot, three-component and efficient process by condensation reaction of barbituric acids, aldehydes and a series of enamines in water. Prominent among the advantages of this new method are operational simplicity, good yields in short reaction times and easy work-up procedures employed. (C) 2009 Elsevier B.V. All rights reserved.
