摘要：
Pyrazolyl-substituted chromene analogues have been synthesized in one pot from 1H-pyrazole-5-carbaldehydes, malononitrile, and cyclohexane-1,3-dione or dimedone in the presence of L-proline as catalyst using ethanol as solvent under reflux conditions for 2-3 h. This approach offers notable advantages such as high yields, environmental friendliness, easy experimental procedure, short reaction time, and mild reaction conditions.
