Patent number: 4764628Abstract: Asymmetric epoxidation of allylic alcohols using carboxylic acid treated phenethyl hydroperoxide oxidate and titanium tartrate catalyst gave optically active glycidols following an enantioselection rule opposite to that observed from the Sharpless epoxidation (U.S. Pat.
