The influence of various parameters including solvent, base and temperature on the reaction between carbazole and epoxides was studied. This led to the development of a regioselective ring-opening of epoxides by the potassium salt of carbazole in DMSO at 100 °C which is a straightforward way to prepare new N-(β-hydroxyalkyl)carbazoles in good to excellent yields. Fifteen new compounds are described
研究了溶剂、碱和温度等参数对咔唑与环氧化物反应的影响。这导致了咔唑钾盐在 DMSO 中在 100 °C 下对环氧化物进行区域选择性开环的发展,这是制备新的 N-(β-羟烷基)咔唑的直接方法,收率良好至极好。描述了 15 种新化合物。
