7-Trifluoromethyl-4-hydroxy quinoline-3-carboxylic acid ethyl ester was prepared from 3-amino benzotrifluoride and EMME. The hydroxyquinoline was reacted with amino acids to furnish amino acid funtionalised quinolines (5, 6, 7). The compounds were alkylated by ethyl iodide followed by hydrolysis afforded the title compounds in good yields. They were screened for their antibacterial activity for in
由3-氨基苯并三氟化物和EMME制备7-三氟甲基-4-羟基喹啉-3-羧酸乙酯。的羟基喹啉与氨基酸反应,得到氨基酸funtionalised喹啉(5,6,7)。将该化合物用碘乙烷烷基化,然后水解,以高收率得到标题化合物。筛选了它们在体外对革兰氏+ ve和革兰氏-ve细菌菌株的抗菌活性,发现11e和11b是有前途的化合物。
