A facile, eco-friendly, and highly efficient one-pot four-component protocol is demonstrated for the synthesis of the pyrano[2,3-c]pyrazole and pyrano[4′,3′:5,6]pyrazolo [2,3- d ]pyrimidine derivatives using magnetized water as a new green solvent. Simplicity, short reaction time, high yield, easy work-up, and absence of hazardous organic solvents are the main advantages of this method .
