Synthesis of coumarins by Pechmann reaction under microwave irradiation and green solvent ionic liquid

  • Received Date: 2009-05-05
  • Objective :To explore an easily-controled,environmentally-benign synthetic method of coumarin derivatives. Methods :Several coumarin derivatives are synthesized from phenols and ethyl acetoacetates by the Pechmann reaction under four different conditions(H2SO4,BiCl3,Microwave/BiCl3,Microwave/ionic liquid). Results :Compared with traditional reaction,present method under microwave and ionic liquid avoids using of organic solvent,shorten the reaction period and obtain a good yield. Conclusion :Microwave accelerated Pechmann reaction using ionic liquid as catalyst is a convenient and green alternative for synthesizing coumarin derivatives.
