  Rapid and efficient synthesis of fused heterocyclic pyrimidines under ultrasonic irradiation

  摘要：

  Some fused heterocyclic pyrimidines have been synthesized in high yields using ultrasound irradiation in a one-pot, three-component and efficient process by condensation reaction of barbituric acids, aldehydes and a series of enamines in water. Prominent among the advantages of this new method are operational simplicity, good yields in short reaction times and easy work-up procedures employed. (C) 2009 Elsevier B.V. All rights reserved.
