Abstract:

A rapid, clean and hight efficient one-pot approach to the series of pyrano[3,2-c]chromenes derivatives were synthesized in short time via multicomponent reaction of three components which are aromatic aldehyde, malononitrile, as well as 4-hydroxycoumarin in the presence of a new material MgO/SBA-15 as a catalyst in solvent-free neat conditions is described. The present method has a beneficial effect of mild reaction conditions, at room temperature, easy isolation of product and nanoparticle catalyst with excellent yields

Keywords: MgO/SBA-15, multicomponent reaction, pyarano[3,2-c]chromenes
