A highly efficient and green protocol has been developed for the synthesis of 4-(1-aryl-2-nitroethyl)-3-methyl-1H-pyrazol-5-ol via Michael addition of 3-methyl-2-pyrazolin-5-one with β-nitrostyrenes under catalyst free conditions on aqueous medium. A series of 4-(1-aryl-2-nitroethyl)-3-methyl-1H- pyrazol-5-ols have been synthesized with good to excellent yield. C-alkylated product was observed exclusively with 3-methyl-2-pyrazolin-5-one without formation of N-alkylated product.

A new method for the synthesis of 2-indolyl-1-nitroalkanes from indoles and β-nitrostyrene via Michael addition catalyzed by [Cu(3,4-tmtppa)] (MeSO4)4 as a reusable catalyst under solvent-free conditions is described. This method has
