Nano SnCl2-SiO2 Catalyzed Facile Synthesis of Aryloylamido Coumarins Derivatives
نویسنده
چکیده مقاله:
A highly efficient and general method for the synthesis of aryloylamido coumarinsderivatives by a three-component condensation of 4-hydroxycoumarin or 4-hydroxy-6-methylpyran-1-one, aryl glyoxals and benzamide in the presence of nano silica supported tin(II) chloride as a heterogeneous catalyst is established. In this method, SnCl2/nano SiO2 wasused as green and reusable catalyst. Excellent yields, short reaction times, simple workup,and inexpensiveness and commercially availability of the catalyst are the advantages of thismethod.
