Résumé

A simple radical-based route to gem-α-dichloroketones, relying on the degenerative addition transfer of (S)-[3,3-dichloro-2-oxopropyl]-O-ethyl dithiocarbonate (xanthate), is described. The adducts can then be converted into Z-enoates by exposure to Et₃N in methanol. In the case of certain substrates, it was possible to form skipped dienoic acid and methyl E,E-dienoates.
