    摘要: 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.
