Microwave assisted synthesis of biologically active 3-hydroxypyridin-4-ones

3-Hydroxypyridin-4-ones (3, 4-HPs) have emerged as important substructures found in many natural and synthetic biologically active materials.1They are investigated as potential antibacterial, antidiabetic, antineurodegenerative and anticancer agents, as well as potential chelators in metal overload conditions.1Our recent investigations of this class of compounds have been focused on their in vitro antiproliferative and antiadhesive activity.2 Although versatile in their biological activities their synthesis remains a challenge. They can be prepared by either the direct or Harris method from maltol or the corresponding aniline derivative with or without the acidic catalyst.2The direct approach consists of heating the reactants in an autoclave for at least 48 h. The second, Harris method, includes the additional steps. We have investigated their microwave assisted synthesis and found it to be an effective and not so time-consuming alternative method for their preparation.
