A direct oxidative route for the synthesis of pyrimidines using heteropolyacids
摘要:
Pyrimidines are synthesized via a direct oxidative one-pot, three-component, reaction between a 1,3-diketone, benzaldehydes and ammonium acetate in the presence of catalytic amounts of Keggin-type heteropolyacids under refluxing conditions in good yields. (C) 2008 Elsevier Ltd. All rights reserved.
