We report that phenacyl azides are key compounds for a regiodivergent synthesis of valuable, functionalized imidazole (32–98% yield) and pyrimidine derivatives (45–88% yield), with a broad substrate scope, when using deep eutectic solvents [choline chloride (ChCl)/glycerol (1:2 mol/mol) and ChCl/urea (1:2 mol/mol)] as environmentally benign and non-innocent reaction media, by modulating the temperature (25 or 80 °C) in the presence or absence of bases (Et3N).
我们报告苯乙酰叠氮化合物是合成有价值的、官能化咪唑(32-98% 收率)和嘧啶衍生物(45-88% 收率)的关键化合物,具有广泛的底物范围,当使用深共熔溶剂 [氯化胆碱(ChCl)/甘油(1:2 摩尔比)和 ChCl/尿素(1:2 摩尔比)] 作为环境友好且非无辜的反应介质时,通过调节温度(25 或 80 °C)在存在或不存在碱(Et3N)的情况下。
