Previous experiments carried out in our laboratory with 6,7-epoxylinalyl acetate afforded good yield of the corresponding seven-membered carbocycle. A Thorpe-Ingold effect exerted by the methyl and acetate group upon C-3 carbon was postulated to rationalize this result, see Ref. 3. For other 7-endo radical cyclizations, see:
