Abstract: We have developed the chloramphenicol base urea-catalyzed intramolecular Michael addition of γ-hydroxy-α, β-unsaturated enones. The oxidation of the resulting products provided facile access to the corresponding α-hydroxy chiral alcohols with good efficiency and enantioselectivity, with… read more here.
