Free radical phenylthio group transfer to nonactivated delta-carbon atom in the photolysis reactions of alkyl benzenesulfenates
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
A free radical phenylthio group transfer from oxygen to the non-activated delta-carbon atom was achieved by irradiation of alkyl benzenesulfenates 1 in the presence of hexabutylditin, and delta-phenylthio alcohols 2 were ...
Free radical mediated construction of small ring compounds: The double annulation of bicyclo[3.1.0]hex-2-enes
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
A free radical approach to fused cyclopropane derivatives is described. Homolytic decomposition of thiohydroxamic esters 4a-e in the presence of dimethyl acetylendicarboxylate affords bicyclo[3.1.0]hex-2-enes 6a-e in ...
