Advances in the Arena of 1-(4-hydroxy-6-Methyl-2H-Pyran-2-On-3-yl)- 3-Arylpropenone: Preparation, Reactivity and Transformations

The 1-(4-hydroxy-6-methyl-2H-pyran-2-on-3-yl)-3-aryl-2-propenones, chalcone analogs derived from dehydroacetic acid (DHA), play a significant role in synthetic organic chemistry and proved to be an important intermediate for the wealth of multifarious biologically active molecules especially heterocyclic compounds. The review is an attempt to compile the transformations of DHA-chalcones to various classes of products.
