by microwave irradiation of equimolar mixture of 4-hydroxythieno[2,3-d]pyrimidines and phosphorus oxychloride. The final compounds were screened for antibacterial activity by Kirby Bauer's method using amicacin as the standard against various gram positive and gram negative bacteria. All the compounds showed antibacterial activity comparable with the standard.
一种新颖,高效的微波辅助路线,用于合成6-取代的2,3,4-三氢嘧啶[1,2-c] -9,10,11,12-四氢苯并[b]噻吩并[3,2-e已经开发了高产率的]嘧啶。中间体2-取代的4- [3-羟基(丙基-1-氨基)] 5,6,7,8-四氢苯并[b]噻吩并[2,3-d]嘧啶是通过照射2-取代的-在碱性条件下,在微波炉中,将4-氯-5,6,7,8-四氢苯并[b]噻吩并[2,3-d]嘧啶与1-氨基丙醇一起使用。通过微波辐射4-羟基噻吩并[2,3-d]嘧啶和氯氧化磷的等摩尔混合物,合成了4-氯噻吩并[2,3-d]嘧啶。使用氨苄青霉素作为标准品,针对多种革兰氏阳性和革兰氏阴性细菌,通过柯比鲍尔(Kirby Bauer)方法筛选最终化合物的抗菌活性。
