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.
Stereoselective reduction of α,β-epoxy ketones with sodium borohydride in the presence of calcium chloride or lanthanum chloride. A practical preparation of erythro-α,β-epoxy alcohols
erythro-Epoxy alcohols were prepared with high stereoselectivity by NaBH4 reduction of the corresponding α,β-epoxyketones in the presence of calcium chloride or lanthanum chloride regardless of the substituents on the epoxide ring.
