Sugar-derived hydroperoxides have been employed for DBU-promoted enantioselective epoxidation reactions. Optimisation studies are reported using 2-(5-cyclohexylpentadienamido)-1,4-benzoquinone (maximum ee = 67%); the resulting epoxide is an important synthetic precursor for the antibiotic (-)-Alisamycin. The procedure has also been applied to a range of 2-substituted naphthoquinones (maximum ee = 82%).
