• Organocatalytic Three-Component Reactions of Pyruvate, Aldehyde and Aniline by Hydrogen-Bonding Catalysts

  Hydrogen-bonding catalysts have been found to catalyze one-pot three-component reactions of pyruvate, anilines and aldehydes to afford versatile 3-amino-1,5-dihydro-2H-pyrrol-2-ones in high yields. Both, thioureas and phosphoric acids are viable catalysts for these reactions and have comparable activity. The corresponding chiral thioureas and phosphoric acids have also been used in these three-component

  Uncatalyzed one-pot pseudo-four-component reaction of ethyl pyruvate, anilines, and aldehydes in n-hexane as solvent, under reflux, affords a variety of 3-amino-1,5-dihydro-2H-pyrrol-2-ones in high yield. n-Hexane is an excellent driving force in preparation of the desired products. These compounds have biological and pharmacological properties and are also used in medicinal chemistry. Use of a non-toxic and inexpensive solvent, simple and efficient synthesis, clean work-up, and high yields of the products are the advantages of this method. We report the first catalyst-free method for synthesis this class of compounds.
