New 1, 2, 4-triazoles (1) having a difluoro(heteroaryl)methyl moiety were designed and synthesized via 1-aryl-2, 2-difluoro-2-(heteroaryl)ethanones (2), which were prepared by two routes starting from the reaction of ethyl 2, 2-difluoro(heteroaryl)acetate with phenyllithiums (Route A) and from the reaction of chlorodifluoro(heteroaryl)methane with benzaldehydes (Route B). The compounds 1 except for 1g show antifungal activities against yeasts and filamentous fungi in vitro, especially (+)-1f have equal or superior activities compared to those of itraconazole.
新型1, 2, 4-三氮唑化合物(1),具有二氟(杂环基)甲基结构,通过1-芳基-2, 2-二氟-2-(杂环基)乙酮(2)的设计与合成而得,该中间体通过两种途径制备:一种是从乙基2, 2-二氟(杂环基)乙酸酯与苯基锂反应开始(途径A),另一种则是从氯二氟(杂环基)甲烷与苯甲醛反应开始(途径B)。除了化合物1g外,所有化合物1均表现出体外抗真菌活性,尤其是(+)-1f,其活性与伊曲康唑相当甚至更优。
