Indium mediates the coupling of alpha-(bromomethyl)acrylic acid with carbonyl compounds in aqueous media to give the corresponding gamma-hydroxy-alpha-methylene carboxylic acids. The reaction has been applied to the syntheses of (+)-3-deoxy-D-glycero-D-galacto-nonulosonic acid and N-acetylneuraminic acid.
