A series of new thiazolyl chalcones, 1‐[2‐amino‐4‐methyl‐1, 3‐thiazol‐5‐yl]‐3‐aryl‐prop‐2‐en‐1‐one were prepared by piperidine mediated Claisen‐Schmidt condensation of thiazolyl ketone with substituted aromatic aldehyde. These chalcones on cyclization gave 2‐amino‐6‐(2‐amino‐4‐methyl‐1,3‐thiazol‐5‐yl)‐4‐aryl‐4H‐pyridine‐3‐carbonitrile and 2‐amino‐6‐(2‐amino‐4‐methyl‐1,3‐thiazol‐5‐yl)‐4‐aryl‐4H‐pyran‐3‐carbonitrile
哌啶介导的Claisen-Schmidt制备了一系列新的噻唑基查耳酮,1- [2-氨基-4-甲基-1,3-噻唑-5基] -3-芳基丙-2-烯-1-酮噻唑基酮与取代的芳族醛的缩合。这些环化的查耳酮产生了2-氨基-6((2-氨基-4-甲基-1,3-噻唑-5-基)-4-芳基-4H-吡啶-3-腈和2-氨基-6( 2-氨基-4-甲基-1,3-噻唑-5基)-4-芳基-4H吡喃-3-腈。结果表明,该骨架框架显示出显着的抗微生物作用。活性最高的抗菌剂是2-氨基-6-(2-氨基-4-甲基-1,3-噻唑-5-基)-4-(4-氯苯基)-4H-吡喃-3-腈,而2-氨基氨基-6(2-氨基-4-甲基-1,3-噻唑-5基)-4-(4-甲基苯基)-4H吡喃-3-腈是最活跃的抗真菌剂。J.杂环化学。(2011)。
