We plan to study the synthesis of Zn2SnO4 nanoparticles via a sol-gel method and evaluate their catalytic activity in the three-component reaction including active enolates, active methylene, and aldehydes leading to the formation of the pyran derivatives. Functionalized pyrano[3,2-c]chromenes and pyrano[4,3-b]pyran derivatives were synthesized via a one-pot, a three-component reaction under ultrasonic irradiation conditions in good to excellent yields. The catalyst was characterized by XRD, FESEM and TEM analyses.
