This invention relates to a method for producing a glycidyl ether of general formula (I), wherein A is an optionally substituted aryl or heteroaryl group and the asterisked carbon atom represents an asymmetric carbon atom, comprising reacting an aryl alcohol of the general formula A-OH, wherein A is as defined above, with an epihalohydrin in the presence of a quaternary ammonium salt and, if necessary, treating the reaction product with a base. This method can afford the glycidyl ether of formula (I), which is useful as an intermediate of drugs, especially a β-blocker, in a simplified manner with a high optical purity.
本发明涉及一种生产通式(I)缩水甘油醚的方法,其中A为任选取代的芳基或杂芳基,星号碳原子代表不对称碳原子,包括在季铵盐存在下,使通式A-OH的芳基醇(其中A如上定义)与表卤代醇反应,必要时用碱处理反应产物。这种方法可以以简化的方式得到式 (I) 的缩水甘油醚,它可以作为药物,特别是 β-受体阻滞剂的中间体,而且光学纯度高。
