Nano crystalline ZnO catalyzed one pot three-component synthesis of 7-alkyl-6H,7H- naphtho[1',2':5,6]pyrano[3,2-c] chromen-6-ones under solvent-free conditions

Nano crystalline ZnO catalyzed one pot three-component synthesis of 7-alkyl-6H,7H- naphtho[1',2':5,6]pyrano[3,2-c] chromen-6-ones under solvent-free conditions

In the present paper, an efficient one-pot synthesis of 7-alkyl-6H,7H-naphtho[1',2':5,6]pyrano[3,2-c]chromen-6-ones is described by three-component reaction of β-naphthol, aromatic aldehydes and 4-hydroxycoumarin using ZnO nanoparticles under solvent-free conditions. The present method pro...
