Electro synthesis of nanoparticles of 4H-pyran from MCRs ofaldehydes, malononitrile and dimedone

An electrochemical strategy for the synthesis of nanoparticles of 4H-pyran is described, using an electro generated base of the anion of propanol in a one-pot, three component condensation of an aryl aldehyde, dimedone and malononitrile in propanol in an undivided cell and in the presence of sodium bromide as an electrolyte at room temperature. The protocol has the advantages of easy work-up, high yields, wide application scope, and an environmentally benign procedure compared with the reported methods.
