  A series of functionalized pyrans fused with quinolones, naphthoquinones, coumarins and pyrones have been synthesized using three component reactions of arylglyoxal monohydrate, malononitrile, and a wide range of cyclic 1,3-dicarbonyls under microwave irradiation. This method is a simple and straightforward method for the easy access of fused and functionalized pyrans tethered with an aroyl group without

  DOI：10.3987/com-14-13006

  日期：——

  A new class of pyrano [3,2-c]coumarins containing an aryloylgroup was synthesized via the three-component reactions of 4-hydroxycoumarin with arylglyoxals and malononitrile. The reactions are efficiently catalyzed by zinc oxide nanoparticles as powerful and recyclable catalyst. The green chemistry principles were also considered and the present method has some advantages, such as simplicity, low catalyst loading, and high yields.

  Aryl glyoxals reacted with malononitrile and 4-hydroxycoumarin in the presence of a catalytic amount of TiO2 nanoparticles to give a hitherto unknown family of pyranochromenes in up to 80% yield. This new three-component reaction yielded some novel pyrano[3,2-c]chromene-5-ones containing an aroyl substituent. Using a recyclable and safe catalyst along with a green solvent system made the process eco-friendly and economic.
