Synthesis of Heterocyclic Compounds from the Reactions of Dehydroacetic Acid (DHA) and Its Derivatives

Abstract

3-Acetyl-4-hydroxy-6-methyl -2-oxo-2H-pyran (Dehydroacetic acid, DHA) and its simple derivatives such as 3-cinnamoyl-4-hydroxy-6-methyl-2-oxo-2H-pyrans (Chalcone analogues of DHA) find interesting applications in the synthesis of various heterocyclic compounds. The review highlighting this aspect covers literature up to 2003.
