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.

Résumé A wide variety of oximes were prepared from different types of alcohols with hydroxylamine hydrochloride using 1-methylimidaziloum nitrate, [Hmim][NO3], ionic liquid as a reaction medium and promoter under microwave irradiation. This protocol provides a one-pot oxime synthesis with high yields that is facile, eco-friendly and the ionic liquid can be recovered and reused.
