ملخص المقالة :

Nano-rice bran/TiCl4has been prepared from rice bran and TiCl4 in n-hexane as solvent. Thennanoricebran/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 kojicacid.Cleanliness, an eco-friendly catalyst, simple methodology, short time, and excellent yields ofproducts are some advantages of this method.
