摘要：

The reaction of aryl-substituted allylic alcohols la-c with Zn(acac)2 using a catalytic amount of PdCl2(PPh3)2 proceeds efficiently in the presence of lithium chloride and titanium(IV) isopropoxide to give the corresponding acetonylated products 3-5. Similarly, benzoylmethylation and ethoxycarbonylmethylation of la and lb can also be attained by using zinc enolates generated in situ from reactions of zinc chloride with dibenzoylmethane 8b and ethyl benzoylacetate 8c.
