Nitroaldol Reaction

β,β-Disubstituted-1,3-dinitro compounds were obtained exclusively with an overall yield of 83% through a domino nitroaldol/elimination/1,4-addition process, when excess nitromethane was added to cyclohexanone or butanone using DBU (1,8-diazabicyclo[5.4.0]undec-7-ene), as a basic catalyst. On the other hand, β-nitroalcohols could be obtained in 30-84% yield, when nitromethane reacts with different aliphatic ketones in stoichiometric amounts, in the presence of catalytic amounts of K2CO3(s), Amberlyst®-A21 or TBAF.3H2O (tetra-n-butylammonium fluoride trihydrate)/THF (tetrahydrofuran). In addition, a new and versatile route to obtainment of allylic nitro compounds, by treatment of acetylated nitroalcohols and aldehydes in catalytic amounts of DBU or TBAF.3H2O, via a one-pot elimination/nitroaldol reaction sequence, was developed.

Imidazole was generated in situ via a domino reaction between glyoxal, formaldehyde, and two units of aqueous ammonia. Aqueous bicarbonate and a carboxylic anhydride or dialkyl dicarbonate were added, yielding the corresponding N,N′-diacyl or N,N′-dicarbalkoxy-2-hydroxyimidazoline. A Bamberger ring cleavage ensued, affording cis-1,2-di(acetamido)ethene, cis-1,2-di(propylamido)ethene, cis-1,2-di(ethoxyamido)ethene, cis-1,2-di(tert-butoxyamido)ethene, or cis-1,2-di(benzamido)ethene as easily isolable solids. The convenience and generality offered by this one-pot approach implied a cost-effective route to the routine synthesis of oligo- and polyvicinalamine precursors.
