Abstract

1,6-Conjugate addition of nitroalkanes to methyl 1,3-butadiene-1-carboxylate, performed with Amberlyst A 27, using microwaves and in the absence of any solvent, allows the prevalent formation of the β,γ-unsaturated adduct, over the α,β-unsaturated one. The products were exclusively obtained as (E)-isomers.
