A method has been developed for the intermolecular hydroacylation of homoallyl alcohols with salicylaldehydes to furnish homoaldol products In 50-98% yields. The method also applies to the hydroacylation of 2-hydroxystyrenes. This work highlights the use of hydroacylation as a unified approach to both aldol and homoaldol products.

A novel Claisen rearrangement reaction is provided. An allylic reactant such as an allylic amine, an allylic ether or an allylic thioether is reacted with an acid chloride in the presence of a Lewis acid catalyst composition composed of a Lewis acid and a base selected from the group consisting of tertiary amines and non-nitrogenous bases. The stereochemistry of the reaction product is readily controlled by the positioning and size of substituents on the allylic reactant. The reaction may be carried out on a solid support, i.e., on the surface of a substrate suitable for conducting solid phase chemical reactions.
