Abstract
Bi(OTf)3 was found to be an efficient, reusable and high yielding catalyst for the synthesis of dihydropyrano[3,2-b]chromenediones via the three-component reaction of aromatic aldehydes, kojic acid and 1,3-diones. The catalyst could be separated and recovered easily, and was reused for several runs without significant loss of its activity. © 2014 Iranian Chemical Society.
