Hypervalent iodine mediated synthesis of 1-aryl/hetryl-1,2,4-triazolo[4,3-a] pyridines and 1-aryl/hetryl 5-methyl-1,2,4-triazolo[4,3-a]quinolines as antibacterial agents

with iodobenzene diacetate (IBD) in dichloromethane yield 1-aryl/hetryl-1,2,4-trizolo-[4,3-a] pyridines (3a-f) and 1-aryl/hetryl-5-methyl-1,2,4-triazolo[4,3-a] quinolines (6a-f). Seven compounds were tested in vitro for their antibacterial activity. 1-(5'-Nitro-2-furyl)-5-methyl-1,2,4-triazolo[4,3-a]quinoline (6e) was associated with substantially higher antibacterial activity than some commercial antibiotics
用二氯甲烷中的碘代二苯乙酸酯(IBD)氧化2-吡啶基和2-喹啉yl,生成1-芳基/ hetryl-1,2,4-trizolo- [4,3-a]吡啶(3a-f)和1-芳基/ hetryl-5-甲基-1,2,4-三唑并[4,3-a]喹啉(6a-f)。体外测试了七种化合物的抗菌活性。1-(5'-硝基-2-呋喃基)-5-甲基-1,2,4-三唑并[4,3-a]喹啉(6e)的抗菌活性明显高于某些商业上针对鼠伤寒沙门氏菌的抗生素。 MIC,即10微克mL(-1)。
