Abstract

Treatment of aryl bromides with homoallyl alcohols bearing a trimethylene group at the allylic position in the presence of cesium carbonate under palladium catalysis affords (2-arylethylidene) cyclobutanes selectively. The selective formation of the alkylidenecyclobutane skeleton results from regiospecific retroallylation of the homoallyl alcohols, which accompanies the transposition of the double bonds.
