honium hydrogen sulfate as catalyst. Structures of all the compounds were established on the basis of analytical and spectroscopic data. All the compounds were evaluated for their in vitro antimicrobialactivity against different bacterial and fungal strains.
一系列的8,9-二氢-2-(2-oxo-2 H -chromen-3-yl)-5-aryl-3 H -chromeno [2,3 - d ]嘧啶-4,6(5 H, 7 H)-二酮(5a-j)是通过2-氨基-5,6,7,8-四氢-5-氧代-4-芳基-4 H-色烯-3-腈(4a – j)在纯条件下,用布朗斯台德酸性离子液体(4-磺丁基)三(4-磺苯基)phosph硫酸氢盐作催化剂,用香豆素-3-羧酸进行催化。所有化合物的结构都是根据分析和光谱数据确定的。对所有化合物进行了体外评估 对不同细菌和真菌菌株的抗菌活性。
