The lithium and potassium salts of 2-vinylcyclobutanols undergo vinylcyclobutane rearrangement at 25–70°, providing an efficient method for the synthesis of 3-cyclohexenol derivatives. 2-Vinylcyclobutanones are prepared from α, β-unsaturated carbonyl compounds by the method of Trost and via [2+ 2]-cycloadditions of olefins and vinylketenes. Addition of hydride or alkyllithium reagents then generates 2-vinylcyclobutanol salts which directly ...
