H3PW12O40 as an efficient catalyst for one-pot- tricomponent synthesis of chromeno[4,3-b]quinolones under microwave irradiation
Some Chromeno[4,3-b]quinoline derivatives were synthesized in a tricomponents one-pot reaction of 1,3-cyclohexadione arylaldehydes and 4-aminocoumarin under Microwave irradiation in the solventless system by using a heteropolyacid catalyst ,H3[PW12O40] in 80-95% yields and high rates. The shorter reaction times, one-pot, good yields, simple work-up procedure and environmentally friendly conditi...

A simple, fast, efficient and environmentally friendly method for synthesis of benzimidazole and its 2-alkyl, aryl and heteroaryl substituted derivatives was developed using zeolite HY. Two component cyclolcondensation of 1,2-phenylenediamine (o-phenylenediamine) and commercially available carboxylic acids catalyzed by zeolite HY without any solvent, under microwave irradiation led to formation...
