The one-pot, three-component cyclization reaction a wide variety of aryl/heteroaryl aldehydes, hydroxylamine hydrochloride, and β-keto ester compounds was performed in simple manner. reactions carried out the presence sodium chloride (NaCl) as profitable, green, efficient catalyst at room temperature. Optimization experiments indicate that amount 17 mol% loaded NaCl is sufficient to catalyze reaction. Among advantages this NaCl-catalyzed method are availability catalyst, no need for synthesis several steps, commercially available reactants, use aqueous conditions, clean synthesis, non-inflammable medium, environmental pollution, safety, cost-effectiveness, pot-economy, optimum efficiency, carbon economy steps. Due absence harmful solvents, an abundant, low-cost, useful water solvent, considered green synthesis.

The one-pot three-component synthesis of 3,4-Disubstituted isoxazole-5(4H)-ones has been developed using an aqueous micellar medium as a catalyst under milder reaction conditions. was completed by 25 mol% sodium lauryl sulfate in at room temperature. employs green solvent, eco-friendly reagent, and non-chromatographic method for purification. present tolerates several substituted aldehydes proved to be efficient along with excellent yield. Moreover, the recovered reused times without significantly losing its catalytic activity.

In this contribution, the propylamine-functionalized cellulose (Cell-Pr-NH2) was employed as catalyst in three-component reaction between hydroxylamine hydrochloride, various type of aryl/heteroaryl aldehydes, ethyl acetoacetate/ethyl 4-chloroacetoacetate/ or 3-oxohexanoate. The results these experiments were formation 3,4-disubstituted isoxazol-5(4H)-one heterocycles. desired five-membered heterocyclic compounds obtained good to high yields at room temperature. investigation different solvents led us conclusion that water is best solvent perform current one-pot, reactions. Attempts find optimum loading clearly showed 14 mg Cell-Pr-NH2 seems be sufficient carry out This method has highlighted some principles green chemistry including less waste generation, atom economy, use an environmentally friendly solvent, and energy saving. Purification without chromatographic methods, mild conditions, simple work-up, low-cost medium, saving time, obtainable precursors are other notable features one-pot fashion.
