Synthesis and characterization of some novel coumarin derivative

Coumarin chemistry has become great important in recent years because of the discovery of the varied biochemical properties industrial uses and analytical applications of these compounds. A considerable amount of work has been done on coumarins and has been reviewed by a number of coworkers. Benzo-2-pyrones commonly known as coumarins are a fascinating group of compounds occurring widely in nature both in free and combined states. Benzo-2-pyrones and benzo-4-pyrones are known as coumarins and chromones respectively.
