Abstract
  In this work, Nano TiO2@KSF used as an efficient, homogeneous and reusable catalyst for the synthesis of pyrano[2,3-d]-pyrimidinone derivatives via three-component reactions between malononitrile, barbituric acid and various aldehydes in water. The products were formed in high yields within short reaction ...  Read More
