Abstract
An eco-friendly method for diversity-oriented synthesis of substituted dihydropyrano[2,3-c]pyrazole and benzylpyrazolyl coumarin derivatives has been achieved via one-pot and multicomponent reaction in the presence of PdO/AlSBA-15 as an efcient and recyclable catalyst in H2O/EtOH under refux conditions.The signifcant merits of this method are wide scope, high yields of the desired products, short reaction times and simple workup procedure. In addition, this nanocatalyst was simply recovered and reused fve times without signifcant loss in catalytic activity and also performance.
