Organocatalytic Michael addition of 1,3-dicarbonyl indane compounds to nitrostyrenes.
To map out the efficient organocatalyst requirements in the Michael addition of 1,3-dicarbonyl indane compounds to nitrostyrenes, a dozen different amino organocatalysts containing a p-toluenesulfonyl group (Ts) have been evaluated; excellent enantio-selectivities (up to er 92:8) were obtained with a primary amine-based Ts-DPEN catalyst and a plausible catalytic reaction mechanism was proposed ...
متن کاملMichael addition of Pyrrole and indole to α,β- unsaturated compounds in the Presence of oxalic acid
A Simple and efficient method for Michael addition of pyrrole and indole to α,β- un saturated compounds has been developed in the presence of oxalic acid under refluxing reaction condition was achieved.
متن کاملApplication of Acidic Ionic Liquid as a Solvent/Catalyst for Preparation of α-Oximinoketones from β-Dicarbonyl Compounds
The selective nitrosation of β-dicarbonyl compounds with sodium nitrite was carried out under1-methyl-3-carboxymethylimidazolium chloride, prepared from N-methylimidazole andchloroacetic acid, as an acidic ionic liquid. The reaction was found to proceed under relativelymild conditions with excellent conversion and selectivity. The ionic liquid was recycled andreused.

Novotný O., Cejpek K., Velíšek J. (2007): Formation of α-hydroxycarbonyl and α-dicarbonyl compounds during degradation of monosaccharides. Czech J. Food Sci., 25: 119–130. The formation of α-hydroxycarbonyl and α-dicarbonyl compounds from monosaccharides (glucose, fructose, arabinose, glyceraldehyde, and 1,3-dihydroxyacetone) was studied in three different model systems comprising an aqueous an...
متن کاملEfficient 1,4-addition of α-substituted fluoro(phenylsulfonyl)methane derivatives to α,β-unsaturated compounds
The 1,4-addition of a monofluoromethyl nucleophile to a variety of alpha,beta-unsaturated compounds has been achieved under mild conditions using either phosphines or potassium carbonate at room temperature. alpha-Substituted fluoro(phenylsulfonyl)methane easily undergoes Michael addition to alpha,beta-unsaturated ketones, esters, nitriles, sulfones, as well as propynoates at room temperature t...
