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 aromatic aldehyde. These chalcones on cyclisation 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
哌啶介导的克莱森-施密特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-酮噻唑基酮与芳香醛的缩合。这些查耳酮在环化后得到2-氨基-6-(2-氨基-4-甲基-1,3-噻唑-5-基)-4-芳基-4H-吡啶-3-甲腈和2-氨基-6-( 2-氨基-4-甲基-1,3-噻唑-5-基)-4-芳基-4H-吡喃-3-甲腈。结果表明该化合物显示出显着的作为抗菌剂的效力。
