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.
