SYNTHESIS OF OPTICALLY PURE α-METHYLENE-γ-LACTONES FROM (+)-R-(4-METHYLPHENYL)-ALKYLSULPHOXIDES
Bravo, Pierfrancesco,Resnati, Giuseppe,Viani, Fiorenza
, p. 2913 - 2916 (2007/10/02)
Optically pure (+)-R-(4-methylphenyl)sulphoxides were lithiated and alkylated with lithium α-bromomethyl acrylate with medium to high diastereoselection; condensation products gave in two steps optically pure α-methylene-γ-lactones.
