New 2-alkyl-5-aryl-(1H)-pyrrole-4-ol derivatives were synthesized via three-component reaction of β-dicarbonyl compounds with arylglyoxals in the presence of ammonium acetate in water at room temperature.

functionally diverse and highly substituted 4‐aminopyrroles directly from aryl methyl ketones, arylamines, and enamines was developed. The reaction involves in‐situ oxidation of aryl methyl ketone to glyoxal, subsequent imine formation by aniline, followed by nucleophilic addition of enamine, and cyclization to afford highly substituted 4‐aminopyrroles. This reaction involved the formation of two C−N

The reaction between N-substituted enamines and phenylglyoxal or glyoxal yielded Delta(2)-pyrrolin-5-ones in moderate to good yields. An uncommon pyrrolo [2,1-b]thiazole derivative was formed as a minor product when a N-(2-mercaptoethyl)enamine was used as the starting reagent. An explanation for the regiochemistry of the reaction is proposed.
