Two new series of Mannich bases, namely, 1-(morpholino)methyl-3-(4-methylthiobenzyl)-4-(substituted arylidene)amino-1,2,4-triazol-5-thiones 3 and 1-(N-methylpiperazino)methyl-3-(4-methylthiobenzyl)-4-(substituted arylidene)amino-1,2,4-triazol-5-thiones 4 have been synthesized by a three-component Mannich reaction (MCR) involving 3-(4-methylthiobenzyl)-4-(substituted arylidene)amino-5-mercapto-1,2,4-triazoles
曼尼希碱的两个新系列,即1-(吗啉代)甲基-3-(4-甲基硫代苄基)-4-(取代的亚芳基)氨基-1,2,4-三唑-5-硫酮3和1-(N-甲基哌嗪子基)甲基-3-(4-甲基硫代苄基)-4-(取代的亚芳基)氨基-1,2,4-三唑-5-硫酮通过三组分曼尼希反应(MCR)合成,其中3-(4 -甲硫基苄基)-4-(取代的亚芳基)氨基-5-巯基-1,2,4-三唑2,甲醛和吗啉/ N-甲基哌嗪。通过元素分析,IR,(1)H NMR和质谱研究对新合成的化合物进行了很好的表征。还针对它们对多种微生物的抗菌和抗真菌活性进行了筛选,本文讨论了此类研究的结果。
