Synthesis of 3‐(3‐nitrophenacyl)thiazolidine‐2,4‐dione 2g and 3‐(substituted phenacyl)‐5‐[3′‐(4H‐4‐oxo‐1‐benzopyran‐2‐yl)‐benzylidene]‐2,4‐thiazolidinediones 4a–g are reported in this paper. These compounds 4a–g were prepared from 3′‐flavone carboxaldehyde and 3‐substituted phenacyl‐2,4‐thiazolidinediones using Knoevenagel reaction. The structures of all compounds were confirmed by IR, 1H‐NMR, mass
合成 3- (3- nitrophenacyl) thiazolidine - 2,4- dione 2g and 3- (located phenacyl) -5- [3' - (4H - 4 - oxo - 1 - benzopyran - 2 - yl) -benzylidene] -本文报道了 2,4-噻唑烷二酮 4a – g。这些化合物 4a-g 是使用 Knoevenagel 反应从 3'-黄酮甲醛和 3-取代苯甲酰基-2,4-噻唑烷二酮制备的。所有化合物的结构均通过 IR、1H NMR、质谱数据和元素分析确认。评估了分子 4a-g 对金黄色葡萄球菌、白色念珠菌、克柔念珠菌、光滑念珠菌和近平滑念珠菌的体外抗菌活性。与氟康唑相比,化合物 4c 和 4f 对克柔念珠菌和光滑念珠菌显示出更好的抑制活性。
