5,6-dihydro-2H-pyran-2-one | C5H6O2 - ChemSynthesis

A mild, catalytic method for the synthesis of 3,4-dihydro-2H-pyrans is described. The FeCl3-catalyzed transformation of aryl- and alkyl β-diketones enables synthetic access to functionalized pyran core structures incorporated in many natural products and biologically active target structures. The method represents a mild alternative to currently available reaction protocols relying on stoichiometric reagents and harsh reaction conditions. This FeCl3-catalyzed transformation has enabled the selective synthesis of α-lapachone in two synthetic transformations and subsequently β-lapachone in three synthetic transformations, which is currently undergoing clinical trials as a potent anticancer agent.

Transition metal ions play an important role in biological systems and often form stable metal complexes with O, N and O, O donor atoms. Coordination chemistry of transition metal ions is the most widely developed field 16, 17 with their metal complexes, exhibiting wide-ranging properties and relevant applications in various fields 18, 19. Metal complexes of imine bases are found to be of great interest in coordination chemistry 20-22 as the biological activity of an imine base sometimes may increase profoundly upon coordination. Considering the importance of DHA and 2‐aminobenzothiazole in various fields we have synthesized novel 3-(1-(benzo[d]thiazol-2-ylimino) ethyl)-6-methyl-2H-pyran-2, 4(3H)-dione (3BTIEMPD) and its metal complexes. These were characterized by various spectro-analytical techniques such as mass, IR, UV-Visible, NMR, SEM, EDX, ESR, TGA and DTA. Further their antibacterial studies were explored to anticipate future plan for in vivo and in vitro studies.
