Abstract
AbstractA simple one‐pot protocol for the synthesis of benzylpyrazolyl coumarin and pyrano [2,3‐c] pyrazole derivatives in the presence of potassium dihydrogen phosphate (KH2PO4) has been developed. This cascade reaction provides many advantages like environmentally benign reaction, mild reaction conditions, inexpensive catalyst, simple operation, easy workup procedure, a wide range of functional groups in good to excellent yields, and no need for column purification.
