Abstract
An efficient synthesis of trans-α-methylene-γ-butyrolactones is disclosed from syn-homoallylic alcohols via the intramolecular mesylate displacement reaction promoted by nearby ester group under the influence of MsCl/Et3N. syn-Homoallylic alcohols were prepared via the In-mediated Barbier reaction of the bromides of Baylis–Hillman adducts.
