thiazolidinglycinamides (7a-f). Methods: The synthesis of 4-oxo-1,3-oxazolidines (9a,b), 1,3-oxazoles (10a,b) and 1,3,4-triazoles (11a,b) was carried out starting from compounds 8a,b. Mannich bases (12a-d and 13a-f) were prepared using three component condensation of compounds 5 and 12a,b and corresponding amines. The synthesis of 16a-c, which were considered as the new analogues of azole class antifungals
背景:由1-(4-氟苯基)哌嗪经两步制备胺(2),然后将其转化为相应的酰肼(4)。酰肼(4)与二硫化碳反应生成相应的1,3,4-恶二唑(5),而酰溴用溴乙酸乙酯处理则产生4-氧代-2-硫代氧代-1,3-噻唑烷化合物(6) 。4与几种醛的四组分缩合得到相应的4-氧代-2-硫代氧代-1,3-噻唑烷二酰亚胺酰胺(7a-f)。 方法:从化合物8a开始合成4-oxo-1,3-oxazolidines (9a,b),1,3-oxazoles (10a,b)和1,3,4-triazoles (11a,b),b。曼尼希碱(12a-d和13a-f)使用化合物5和12a,b与相应的胺的三组分缩合制备。从化合物14a开始,通过三个步骤进行了16a-c的合成,这被认为是唑类抗真菌剂的新类似物。 结果与结论:所有反应均在传统和微波辐射条件下进行,并确定了最佳条件。筛选了新合成的化合物的抗菌活性,某些被测化合物表现出良好的中等抗菌活性。
