摘　　要：We have developed an asymmetric ring opening reaction of oxabenzonorbornadienes with substituted phenolic nucleophiles. Under the reaction conditions （ [Rh（COD）C1]2 （1 mol%）, （S）-（R）-PPF-P^Bu2 （2 mol%）, THF, reflux）, the reaction products were obtained with high yield and enantiomeric excesses （ up to 99% ee）.We have developed an asymmetric ring opening reaction of oxabenzonorbornadienes with substituted phenolic nucleophiles.
