Diversity oriented green synthesis of novel benzoxazole clubbed chromene arylsulfonamide derivatives using reusable catalyst

A group of novel heterocyclic arylsulfonamide derivatives were synthesized by three steps process using the organic and inorganic catalyst in less solvent at ambient temperature. One out three-steps process, one-pot multiple component reaction reusable catalyst. These compounds reactions proceed through Knoevenagel condensation accompanied Michael addition to obtaining suspicious products. The compound’s structure was characterized spectral data (UV-vis, FTIR 1H-NMR). Subsequently, obtained final products are “benzoxazole clubbed chromene aryl sulfonamide derivatives”. green synthesis used obtain optimum yield fulfil required conditions such as nontoxic, inexpensive, minimum
