A novel, metal-free process for the challenging synthesis of 2-(3-methyl-1H-1,2,4-triazol-1-yl) acetic acid is reported, which features an efficient construction of the triazole ring under flow conditions. This continuous, one-pot method is atom economical, highly selective and environmentally benign, due to the avoidance of chromatography and isolation steps. Compared to the earlier batch routes,
报道了一种新颖的,无金属的方法,该方法具有挑战性地合成2-(3-甲基-1 H -1,2,4-三唑-1-基)乙酸,该方法具有在流动条件下有效构建三唑环的特征。条件。由于避免了色谱和分离步骤,这种连续的一锅法是原子经济的,高度选择性的且对环境无害的。与早期的批处理路线相比,在流动反应器中获得了更高的产量。另外,可以以安全的方式控制和处理高能中间体。为了概括确定的路线,在上述条件下制备了几种三唑,证实了该方法可以为快速和可持续地构建差异官能化的1,2,4-三唑提供有用的应用。
