Abstract
Methyl α-methoxycarbonyl-β, β-dimethyl-γ-nitrobutyrate adds to methyl acrylate by the Michael's reaction at its γ-carbon atom, in contrast to ethyl α-acetyl-β, β-dimethyl-γ-nitrobutyrate which, in the analogous reaction, adds at the α-carbon atom. The structure of the compounds obtained has been established on the basis of their NMR spectra.
