A variety of acrylicesters, including those derived from Baylis–Hillman reactions, react with NaNO2–ceric ammonium nitrate to form the corresponding β-nitro alcohols 2 and 5 whose dehydration, via their mesylates, leads to β-nitro acrylicesters, in good to excellent yields. Further, β-nitro acrylicesters containing a mesylate group 6, obtained from the Baylis–Hillman products, react with NaN3 to
