Some novel 7-[2- or 3-(cyanomethyl)piperazinyl]quinolones have been prepared. Most notable, 2-cyanomethyl-piperazine 5 and 1-methyl-2-cyanomethylpiperazine 8 at the quinolone C-7 position produce products with good in vitro antibacterial activity. The key step in the synthesis of these products involves the regioselective deprotection of the benzyl group in function of the time reaction.
已经制备了一些新颖的7- [2-或3-(氰甲基)哌嗪基]喹诺酮。最值得注意的是,在喹诺酮C-7位置的2-氰基甲基-哌嗪5和1-甲基-2-氰基甲基哌嗪8产生具有良好体外抗菌活性的产品。合成这些产物的关键步骤包括根据时间反应对苄基进行区域选择性脱保护。
