Exploring the Use of the Suzuki Coupling Reaction in the Synthesis of 4′-Alkyl-2′-hydroxyacetophenones

Abstract : A series of 4′-alkyl-2′-hydroxyacetophenones were prepared by Suzuki cross-coupling reactions of 4′-bromo-2′-hydroxyacetophenone. In these reactions, alkyl(trifluoro)borates were found to be better reactants than alkylboronic acids. 4′-Alkyl-2′-hydroxyacetophenones are key intermediates for the further synthesis of -lipoflavonoids that are more readily incorporated into lipid bilayer membranes than flavonoids and should, therefore, have superior -biological effects through increased bioavailability.
