Novel Chalchone Derivetives

The chemistry of chalcone has been recognized as a significant field of study.Chalcones are the compounds where aromatic substituent are introduced into the terminal position of the system -C=C-C=O. So, chalcones are characterized by their possession of a structure in which two aromatic rings A and B are linked by an aliphatic three-carbon chain [(A) Ar-CO-CH=CH-Ar (B)]. An interesting feature of chalcone is that it serves as starting materials for the synthesis of various heterocyclic compounds such as pyrimidines, pyrazolines, pyrazoles, flavones, flavonols, flavanones, aurones and benzoyl coumarones as well as certain compounds like deoxybenzoins and hydantoins, which are of some therapeutic value.
