used for the preparation of the thiazolylquinolones. The thiazolidinylquinolones were synthesized by quaternization of the corresponding thiazolyl analogues, followed by reduction of the obtained thiazolium salts with sodium borohydride in aqueous solution. Antibacterial activity was tested in vitro. The compounds were inactive against Gram-negative bacteria but some of them showed good activity against
合成了一系列6-取代的-1-乙基-1,4-二氢-4-氧代-7-(2-噻唑基-和噻唑烷基)和喹啉-3-羧酸。在6位上的取代是H,F或Cl。汉茨法用于制备噻唑基喹诺酮。通过将相应的噻唑基类似物季铵化,然后用水溶液中的硼氢化钠还原获得的噻唑鎓盐,来合成噻唑烷二基喹诺酮。在体外测试抗菌活性。该化合物对革兰氏阴性菌无活性,但其中一些对革兰氏阳性菌和分枝杆菌具有良好的活性。在喹诺酮类抗菌剂中很少发现这种活性模式。
