  Polyfunctional 4-(3-cyanopyridin-2-ylthio)acetoacetates were used in the synthesis of 4-hydroxy-1H-thieno[2,3-b:4,5-b]dipyridin-2-ones. The latter were used in reactions with arylidene-malononitriles or in three-component reactions with aldehydes and malononitrile to give 2-amino-4-aryl-3-cyano-5-oxo-5,6-dihydro-4H-pyrano[2,3-d]pyrido[3',2':4,5]thieno[3,2-b]pyridines.
