7,5-Unsaturated aldehydes having a quaternary centre in either the ct or ~-position, have been prepared from substituted y-butyrolactones and undergo efficient 4-exo-trig ketyl-olefin cyclisation on treatment with samarium(II) iodide to give functionalised cyclobutanols. In all cases cyclisation occ
