The sulfenylation-dehydrosulfenylation method, combined with carbon-carbon bond forming reactions, has been applied to the synthesis of some α-functionalized cyclohexenones 3.Hence, the sodium anion of the 2-methylthiocyclohexanone in THF reacts with primary, allyl and benzyl halides as well as with Michael acceptors to lead to the tertiary ketosulfides 1a-j.Further oxidation by NaIO4 and thermolysis in boiling toluene of the resulting sulfoxides 2 have been performed.The scope and limitations of this strategy are also discussed. Key Words: α-functionalized cyclohexenones; tertiary ketosulfides and ketosulfoxides; sulfenylation and deshydrosulfenylation; thermolysis.

Above 100 deg C 5-methylenespironon-1-ene, 1, undergoes cyclobutene ring opening to (E)-triene 2 and apparent 1,3-shift to a hexahydronaphthalene, 3, in a 3 to 1 ratio. (E)-triene 2 gives 3 in a competitive reaction.The activation energies for all th
