Remarkable Effect of a Silicon Group on the Stereoselectivity of Radical 5-exo-Trig Cyclizations

(Matrix presented) Sulfonyl radical mediated 5-exo-trig cyclization of chiral 3-silylhepta-1,6-dienes has been shown to provide cyclopentanes having up to four stereogenic centers with an unexpectedly high level of stereocontrol.

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.
