Reduction of α,β-epoxyketones under the Luche conditions with NaBH4/CeCl3 in MeOH provides anti- (or erythro-) α,β-epoxyalcohols in high yields and with extremely high stereoselectivity.

Sulfur ylides react with monoacetals of α-dicarbonyl compounds to give the expected epoxyacetals in satisfactory to high yields. These lead to α-epoxyketones by chemoselective hydrolysis by acidic moist silica gel.
