x-Haloalkylphenyl sulfones are efficiently aUylated using allyltributyltin in benzene at reflux in the presence of AIBN. Several functional groups (e.g. ester, keto, amino, niVro etc.) are tolerated by these conditions that ultimately allow the cbemoselective allylation of phenylsulfones at ct position.

Sulfination of brorrrodifluoroacetate or acetaitiide 1 with sodiurrr dithionite gives the corresponding sulfinates 2a and 2b, respectively, which upon cuprous bromide catalyzed allylation afford the allylsulfonyldifluoroacetate and acetatnides. Phenyl-or alkylsulfonyldifluoroacetates and acetamides
lsopropenyl-5-membered-ring acetal or lactone are potential precursors of (\_+)-botryodiplodin (1). Several pathways, involving 5-exo-trig ring closure onto allylic sulfones, have been in,.estigated. The iodine atom transfer methodology allowed the preparation of the desired skeleton through intram
