The kinetic resolution of tertiary hydroperoxides via catalytic Sharpless epoxidation with various allylic alcohols has been investigated. By using 1-cyclohexyl-1-phenylethyl hydroperoxide an enantiomeric excess (e.e.) of up to 29 % of the resolved hydroperoxide has been observed at a consumption of the racemic hydroperoxide of nearly 50 %. The e.e. can be increased, however, only by raising the hydroperoxide consumption.
