Homoallylic alcohols were efficiently epoxidized to the corresponding 3,4-epoxy alcohols in excellent yields in the presence of methyltrioxorhenium (MTO) as catalyst, aqueous hydrogen peroxide as the terminal oxidant, and 3-methylpyrazole as an additive. Organic solvent-free conditions accelerate the reaction.
