A variety of α,β-unsaturated ketones effectively reacted in an efficient chromium(III) chloride-catalyzed Michael-type addition with either water or alcohols to give the corresponding β-hydroxyl ketones or β-alkoxyl ketones in good yields with excellent functional group compatibility. The approach was further utilized for the preparation of synthetically useful tetrahydrofuran derivatives.
