A new method of appending seven- and eight-membered rings to cycloalkenes is described.Treatment of selected alkene precursors with an ω-bromoalkyl ketene or a keteniminium salt leads to haloalkyl cyclobutanone formation.Tri-n-butyltin hydride promoted ring expansion then yields the annulated product.Since the initial cyclobutanone is cis fused, the final product is also produced stereospecifically with a cis ring fusion.
