In the presence of a catalytic amount of CuCl and a stoichiometric amount of diisopropylethylamine, methyl α-(bromomethyl)acrylate (1) reacted with trichlorosilane to afford an organosilicon intermediate (2). The intermediate reacted with aldehydes in the same pot to give the corresponding α-methylene-γ-hydroxyesters (3), which were readily converted to α-methylene-γ-lactones (4).
