MILD AND CONVENIENT EPOXIDATION OF α,β-UNSATURATED KETONES BY AMBERLYST A-26 SUPPORTED HYDROPEROXIDE

Abstract

The epoxidation of α,β-unsaturated ketones to the corresponding epoxy ketones, using amberlyst A-26 supported hydroperoxide, which is prepared in situ from (35%) hydrogen peroxide and amberlyst A-26(OH⁻), is described. Reactions were carried out at room temperature and the corresponding epoxides were isolated in excellent yields.
