A one-pot procedure was developed for synthesis of a new series of pyran-2-one products, based on the combination of cyclohexanone with malononitrile and aromatic aldehydes. Reactions take place in an aqueous alcoholic medium at elevated temperature in relatively short time periods, directly giving the products by spontaneous precipitation in the vessel. The final formation of the aromatic pyran-2-one
