Several new 1,5-diaryl-3-(arylamino)-1H-pyrrol
-2(5H)-ones were synthesized via the three-component condensation
reaction of aldehydes, aromatic amines, and ethyl
pyruvate under catalyst-free and solvent-free conditions.
Also, 5-(4-hydroxyl-3-nitrophenyl)-1-(4-methoxy-phenyl)-
3-(4-methoxyphenylamino)-1,5-dihydro-pyrrol-2-one was
synthesized using oxime instead of aldehyde. The ecofriendly,
simple procedure, green procedure, catalyst-free
and solvent-free conditions, short reaction times, and high
yields of the products are the advantages of this method.
