presented. This procedure shows broad substrate scope. Compared with the traditional method of obtaining oxazoles, using substituted chalcones and ammonium oxalate can make the reaction milder and cheaper. Notably, the reaction proceeds smoothly under the system of I2/TBHP, which is very friendly to the environment.
介绍了用于构建 2,5-二取代恶唑的非金属催化氧化环化序列。该过程显示了广泛的底物范围。与传统的获得恶唑的方法相比,使用取代的查尔酮和草酸铵可以使反应更温和,成本更低。值得注意的是,在I 2 /TBHP体系下反应进行顺利,对环境非常友好。
