Abstract
  An improved rapid one-pot and green synthesis of substituted pyranopyranes by condensing Kojic acid, malononitrile, and different aldehydes and using a catalytic amount of cobalt nanoparticles as green and reusable catalyst is reported for the first time. The reaction proceeds in aqueous media at ambient ...  Read More
