The synthesis of 10–15 membered α-methylene macrocyclic lactones from the functionalised allylstannanes (7e)–(7j) is described. Attempts to synthesise analogous 6–9 membered lactones proved unsuccessful, resulting instead in the production of dilactones and AIBN derived adducts.

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 intramolecularSH2′ reaction.
