[ 1 ] - Nano SnCl2-SiO2 Catalyzed Facile Synthesis of Aryloylamido Coumarins Derivatives
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 yie...
[ 2 ] - BF3-SiO2 Nanoparticles: An Efficient Catalyst for the Multi-Component Synthesis of 3-(α-aroylamido) 4-hydroxycoumarin Derivatives in Water
A green and efficient one-pot three component reaction of 4-hydroxycoumarin or 1,3-dimethylbarbutyric acid, aryl glyoxals and amides (thioacetamide) has been developed in the presence of BF3- SiO2 nanoparticles in water. This method has several advantages such as high to excellent product yields in short reaction time, atom economy, environment friendly, reusable catalyst and no need for chroma...
