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 activated alkenes. The carbon radical generated at the dioxolane ring adds stereoselectively to olefins to give the addition products with retention of configuration.
L-(+)-酒石酸的新衍生物已通过可见光光解N-羟基-2-硫代吡啶酮酯,由2,3-O-异亚丙基(R,R)-(+)-酒石酸酯合成活化烯烃存在下的衍生物。在二氧戊环环上产生的碳自由基立体选择性地加成至烯烃,以使加成产物保持构型。
