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. Most of the compounds were inactive against Gram-negative bacteria but some of them showed however good
合成了一系列的7-(2-取代的4-噻唑基和噻唑烷基)-1-乙基-1,4-二氢-4-氧代喹啉-3-羧酸及其6-氟类似物。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。大多数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显示出良好的活性。在喹诺酮类抗菌剂中很少发现这种活性模式。
