A series of new polysubstituted derivatives of 2-tetralones possessing two ester groups were synthesized via a tandem aldol condensation-Diels–Alder-aromatization sequence of reactions. All the three steps took place in one pot and in the presence of aminofunctionalized silica coated Fe3O4 nanoparticles as the catalyst. In situ formed dienes reacted with diethyl acetylenedicarboxylate at room temperature

An excellent regio‐, and enantioselective 1,6‐addition of (nitromethyl)benzenes to α, β, γ, δ‐cyclic dienones through nitro‐Michael reactions has been developed to construct chiral ε‐nitro ketene compounds.
