5-溴嘧啶衍生物的微波绿色合成
Microwave-assisted Green Synthesis of 5-bromo Pyrimidine Derivatives
【摘要】 在水溶液中嘧啶衍生物经微波辐射与Br2快速发生溴代反应,产率较高制得5-溴代嘧啶衍生物(76%~94%),其结构经1H1、3C NMR和元素分析证实.
【Abstract】 The facile bromination of pyrimidine derivatives with Br2 in water under microwave irradiation is described.The desired 5-bromo pyrimidine derivatives(2a2e) were obtained within 10 minutes in 76% 94% yields.Their structures were characterized by 1H,13C NMR and elemental analysis.
