Free radical addition reactions of allylic sulfones to alkenes
Harvey, Iain W.,Phillips, Eifion D.,Whitham, Gordon H.
, p. 6493 - 6508 (2007/10/03)
Intermolecular radical reactions involving formal addition of the sulfonyl and allyl fragments of an allylic sulfone across the double bond of an alkene are described. Reactions are most successful when the allylic sulfone has an electron withdrawing group at the 2-position. Only monosubstituted alkenes give useful yields of adducts, though both electron withdrawing and electron donating substituents are effective.
Radical Reactions in Synthesis: Intramolecular SH2' Macrocyclisations
Baldwin, Jack E.,Adlington, Robert M.,Mitchell, Mark B.,Robertson, Jeremy
, p. 1574 - 1575 (2007/10/02)
The synthesis of 10-15 membered α-methylene lactones 1 from the functionalised allyl stannanes 2 occurs cleanly in moderate to high yield under free radical conditions via an intramolecular SH2' reaction.
