1-trifluoromethyl-4-quinolone derivatives (8a,b) were synthesized, and the antibacterial activity of each was evaluated. An oxidative desulfurization-fluorination reaction was employed to introduce a trifluoromethyl group at the N-1 position as a key step. Among the derivatives, 8a was found to exhibit antibacterial activity comparable to that of norfloxacin (1) against Staphylococcus aureus Smith, Streptococcus pneumoniae
合成了新型的1-三氟甲基-4-喹诺酮衍生物(8a,b),并评估了它们的抗菌活性。作为关键步骤,采用氧化脱硫-氟化反应在N-1位引入三氟甲基。在这些衍生物中,发现8a对金黄色葡萄球菌史密斯,肺炎链球菌IID1210和大肠杆菌NIHJ JC-2具有与诺氟沙星(1)相当的抗菌活性。
