Ammonium Metavanadate: A Mild and Efficient Catalyst for the Synthesis of Coumarins
Mandhane, Priyanka G.,Joshi, Ratnadeep S.,Ghawalkar, Anant R.,Jadhav, Ganesh R.,Gill, Charansingh H. Korean Chemical Society 2009 Bulletin of the Korean Chemical Society Vol.30 No.12
A mild and efficient method has been developed for condensation of substituted phenol with ${\beta}$-ketoester in the presence of catalytic amount of ammonium metavanadate (10 mol%) at ambient temperature to afford the corresponding substituted 4-methyl-2H-chromen-2-one in high yields under mild conditions. Utilization of commercially available inexpensive catalyst makes this manipulation very interesting from an economic perspective.
