摘　　要：利用β-环糊精对底物的包络作用,经由Fries重排反应选择性合成了邻羟基苯乙酮。实验结果表明,加入β-环糊精能够提高重排反应的选择性,使邻羟基苯乙酮收率达到44.6%。Using the inclusion action of β- Cyclodextrin with phenyl acetate, 2 - Hydrexy - acetophenone was Synthesized via Fries rearrangement reaction. The results indicated that it could improve the selectivity of Fries rearrangement reaction by adding β-Cyclodex- trin. The yield of the ortho - product reached 44.6%.
