An anti-selective direct catalytic asymmetric aldol reaction of 2-hydroxyacetophenones with aldehydes is described. The reaction is catalyzed by a heteropolymetallic complex to afford anti-α,β-dihydroxy ketones as the major diastereomer with excellent enantioselectivity. The use of 2-hydroxyacetophenones bearing electron-donating groups at the phenyl moiety enabled efficient transformation of the aldol products (α,β-dihydroxy ketones) into the corresponding α,β-dihydroxy ester derivatives via Baeyer-Villiger oxidation. A plausible reaction mechanism is also discussed based on the stereochemistry of the products.
