Nitroalkanes add to cyclic and acyclic enones in an enantioselective manner in the presence of catalytic quantities of L-proline and trans-2,5-dimethylpiperazine as excess additive.
A convenient solvent-free synthesis of γ-nitroketones and γ-nitroesters based on the reaction of nitroalkanes with α,β-unsaturated carbonyl compounds in the ultrasonically activated heterogeneous catalytic system 1-butyl-3-methylimidazolium tetra-fluoroborate ([bmim][BF4])/K2CO3 has been developed. The system retained its catalytic activity over three reaction cycles.
Polystyryl-BEMP as an Efficient Recyclable Catalyst for the Nucleophilic Addition of Nitroalkanes to α,β-Unsaturated Carbonyl Compounds under Solvent-Free Conditions
3-dimethylperhydro-1,3,2-diazaphosphorine supported on polystyrene (PS-BEMP) is an efficientcatalyst for the addition of nitroalkanes (1–1.5 equiv.) to α,β-unsaturated carbonyl compounds (1.0 equiv.) in the absence of a reaction medium (solvent-freeconditions). The corresponding γ-nitro carbonyl compounds have been isolated in excellent yields but the catalyst can be satisfactorily recovered and used for only 3 times

Judiciously selected conditions of controlled potential electrolysis, at a mercury cathode in aqueous organic media, of γ-nitroketones result in quantitative yields of 1-pyrroline 1-oxides, pyrrolines or pyrrolidines.
