Further Radical Induced Cyclisations of Unsaturated Sulfones

Radical induced cyclisations of unsaturated sulfones by the endo-5-exo- and the exo-5-exo-ipso-modes are described.Thus the unsaturated allylic sulfones 4, 6 and 8 underwent cyclisation to the cyclopentyl sulfones 5, 7, and 9 and 10 respectively, while th

Radical induced 1,3-rearrangement-cyclisations of some unsaturated allylic sulphones

1,3-Rearrangement-cyclisation of unsaturated allylic sulphones, typified by the conversion of the pentenyl substituted allyl sulphone (6) into the cyclic sulphone (8), is described. Reaction is considered to occur by a radical chain mechanism involving addition-elimination of ArSO2*. The scope of the reaction has been explored, using various methyl substituted substrates of type (13) and other structural variants, and found to be quite general.

The Radical-induced Cyclisation of Some Unsaturated Allylic Sulphones

Conditions are described which promote the isomerisation of some suitably constituted unsaturated allylic sulphones to products derived apparently by a radical chain cyclisation mechanism.
