Amine modified nanozeolites for the three component synthesis of chromenes

Abstract: New amine modified nanozeolites were prepared and characterized using FT-IR, TGA, DTG, SEM, and TEM. Then the synthesized nanozeolites were employed as novel, recyclable and safe catalysts for the one-pot, three-component condensation of 4-hydro

One-Pot Synthesis of 4 H -Pyrano[3,2- c ]coumarin Derivatives Catalyzed by Deep Eutectic Solvent

4H-Pyrano[3,2-c]coumarin derivatives are an important class of pharmaceutical compounds that are expensive to prepare by previously reported methods. An efficient and green method was developed to obtain these derivatives using the deep eutectic solvent (
