Abstract :
Nano-rice bran/TiCl4has been prepared from rice bran and TiCl4 in n-hexane as solvent. Thennanorice bran/TiCl4 has been introduced as a novel catalystfor the three component synthesis of pyrano [3,2-b] pyransfrom the simple one-pot reactionbetweenaryl aldehydes,cyanoacetamide and kojic acid.Cleanliness, an eco-friendly catalyst, simple methodology, short time, and excellent yields of products are some advantages of this method.
