  Synthesis of Aroyl[bis(4-Hydroxycoumarin-3-yl)]Methane Using Tungstate Sulfuric Acid in Water

  摘要：

  An efficient synthesis of some new aroyl[bis(4-hydroxycoumarin-3-yl)] methanes (dicoumarols) based on the reaction of 4-hydroxycoumarin with arylglyoxals is described. The reactions were efficiently catalysed by tungstate sulfuric acid to afford the product in moderate to good yields (up to 65%).
