Abstract
A series of new pyrazolo[5,4-b]quinoline derivatives were synthesized in good yields by tin(II) chloride dihydrate catalyzed cyclocondensation of 5-amino-3-(arylamino)-1H-pyrazole-4-carbonitriles with cyclohexane-1,3-dione or dimedone. The synthetic procedure can be carried out by means of simple operations under convenient solvent-free conditions.
