Reaction between aromatic aldehydes and 3–methyl–1–phenyl–2–pyrazoline–5–one catalyzed by nano–SiO2\HClO4 in water under reflux provided a simple and efficient route for the synthesis of 4–((5–hydroxy–3–methyl–1–phenyl–1H–pyrazol–4–yl)(aryl)methyl)–3–methyl–1–phenyl–1H–pyrazol–5–ol derivatives in high yields.

Novel method for the synthesis of 3,3–diindolylindoline–2–ones using nano–Fe(3)O(4)
A facile and convenient protocol was developed for the synthesis of 3,3–di(indolyl)indolin–2–ones in low reaction times and high yields using nano–Fe3O4 as an efficient recyclable heterogeneous catalyst.
Novel method for the synthesis of pyrazolopyridines using nano–Fe(3)O(4)
A multicomponent reaction for the synthesis of pyrazolo [4, 3–e] pyridines from 3–amino–5–methylpyrazole, indan–1, 3–dione and aldehydes using nano–Fe(3)O(4) as an effective andreusable catalyst is reported. The present methodology offers several...
Electrosynthesis 10,11–dihydrochromeno[4,3–b]chromene–6,8(7H,9H)–dione derivatives in the presence of sodium floride as an electrolyte.of
Electrochemically induced catalytic multicomponent transformation of 4–hydroxy coumarin,arylaldehyde and cyclic 1,3–dicarbonyl compounds in alcohols in an undivided cell in the presence of sodium floride as an electrolyte results in the formation of...
Facile one–pot multicomponent synthesis of 2–amino–6–(2–oxo–2H–chromen– 3–yl)–4–arylpyridine–3–carbonitriles using Brønsted acidic ionic liquid as catalyst under solvent–free conditions
A series of 2–amino pyridine–3–carbinitrile derivatives incorporated coumarin moiety has developed via multicomponent condensation of 3–acetyl–2H–chromen–2–one, arylaldehydes, malononitrile and ammonium acetate utilizing Brønsted acidic ionic liquid,...
Selective and efficient synthesis of 3–indolyl–2–oxindoles under catalysis of LiClO4
An efficient and convenient protocol for synthesis of 3–hydroxy–3–indolyl–2–oxindoles and 3,3–diindolyl–2–oxindoles is presented here. The syntheses were achieved selectively under catalysis of LiClO4 whereby the products were obtained purely.
