A reactionbetween epoxides and benzylboronic acid pinacolesters is described. CuI was found to be an effective catalyst of this transformation upon activation of the benzylboronic ester with an alkyllithium reagent. The reaction was very efficient and a variety of substituted epoxides were found to be good substrates with good regioselectivity for substitution at the less substituted side of the

The epoxides were obtained from substituted phenols and epichlorohydrin by reported methods. The regioselective ring opening of epoxides were studied in different solvents by reaction with Grignard’s reagent in presence of dilithium tetrachloromanganate.
