Abstract: We revealed a catalyst-free, green and rapid one-pot four-component tandem strategy for the preparation of dihydropyrano[2,3-c]pyrazoles – a biologically significant scaffold – via Knoevenagel-Michael cyclocondensation based on green chemistry p

6-Amino-4-aryl-3-methyl-5-cyano-1H,4H-pyrazolopyrans were synthesized by the reaction of aromatic aldehydes, malononitrile, and 3-methyl-5-pyrazolone and also of arylidenemalononitriles with 3-methyl-5-pyrazolone or of 4-arylidene-3-methyl-5-pyrazo
