[reaction: see text] Practical reaction conditions for the catalyticenantioselective synthesis of sulfinate esters are reported. Commercially available cinchonaalkaloids were found to be superior catalysts for the sulfinyl transfer reaction of tert-butanesulfinyl chloride and a variety of benzyl alcohols. Sulfinyl transfer with 2,4,6-trichlorobenzyl alcohol and 10 mol % of the commercially available
