New derivatives of L-(+)-tartaric acid have been synthesized from the monomethyl-2,3-O-isopropylidene (R,R)-(+)-tartrate by visible light photolysis of its N-hydroxy-2-thiopyridone ester derivative in presence of activate alkenes. The carbon radical generated at the dioxolane ring adds stereoselectively to olefins to give the addition products with retention of configuration.

Alkyl radicals, derived from decarboxylation of carboxylic acids, add readily to phenyl vinyl sulphone and vinyl phosphonium bromide.The adducts may be further converted into a variety of useful synthetic intermediates.
