Journal ArticleDOI
Synthesis of Novel 2, 3‐Disubstituted 1, 6‐Dihydropyrrolo [2,3‐ g ]indazole Derivatives via One‐pot Three Component Reactions
TL;DR: In this article , a concise and efficient synthetic approach was developed for the synthesis of functionalized 2,3disubstituted 1,6-dihydropyrrolo[2,3-g]indazole via a one-pot, three-component reaction of 1H-indazol-6-amine, arylglyoxal monohydrates, and 4-hydroxy-2H-chromen-2-one or 4hydroxyquinolin-2(1H)-one promoted by acetic acid in ethanol under reflux conditions.
Journal ArticleDOI
An efficient one‐pot synthesis of Spiro[indoline‐3,11′‐pyrazolo[3,4‐f]pyrimido[4,5‐b]quinoline] derivatives
TL;DR: An efficient procedure for the synthesis of novel spiro[indoline-3,11′-pyrazolo[3,4-f]pyrimido[4,5-b]quinoline] derivatives has been developed by one-pot condensation of 1H-indazol-6-amine, isatin and barbituric acid or 2-thiobarbiturate acid, in the presence of L-proline in refluxing EtOH as discussed by the authors .
