Summary:We report an intermolecular hydroacylation of allylic alcohols with salicylaldehydes to afford -hydroxy aryl ketones in 7394% yields as single regioisomers. The reactivity and regioselectivity were promoted by catalytic amounts of a phosphinite that forms a dynamic covalent bond with the allylic alcohol. Hydroacylation of 1,2- and 1,1-disubstituted olefins generates -hydroxy aryl ketones bearing tertiary and quaternary centers, respectively. By applying cooperative catalysis, we achieve a regioselective hydroacylation of allylic alcohols to afford formal aldol products.
