  Synthesis and antibacterial evaluation of 6-azapyrimidines with α-methylene-γ-(4-substituted phenyl)-γ-butyrolactone pharmacophores

  摘要：

  A series of 6-substituted 2-[(4-methylene-5-oxo-2-(4-substituted phenyl) tetrahydrofuran-2-yl)methyl]-1,2,4-triazine-3,5(2H,4H)-diones (5, 6) and 2,4-bis[(4-methylene-5-oxo-2-(4-substituted phenyl) tetrahydrofuran-2-yl)methyl]-1,2,4-triazine-3,5(2H,4H)-diones (9, 10) were designed, synthesized, and evaluated for antibacterial activity against Gram-positive and Gram-negative microorganisms. The synthesis of these compounds involved the Reformatsky-type reaction between ethyl alpha-(bromomethyl)acrylate and the proper ketones. Among these compounds, 2-[(4-methylene-5-oxo-2-phenyl tetrahydrofuran-2-yl)methyl]-1,2,4-triazine-3,5(2H,4H)-dione (5a) is the most active compound and shown the selective inhibition activity against Proteus vulgaris.

  An efficient and convenient method to synthesize 6-oxyalkylated 1,2,4-triazine-3,5(2H, 4H)-diones has been developed via visible-light-induced cross-dehydrogenative coupling reaction between 1,2,4-triazine-3,5(2H, 4H)-diones and ethers with a wide range of functional group tolerance. The present transformation employs the cheap and low-toxic 2-tert-butylanthraquinone as a metal-free photocatalyst and

  1,2,4-3,5 (2 H , 4 H )-二酮类化合物通过可见光诱导的1,2,4之间的交叉脱氢偶联反应合成6-氧烷基化1,2,4-三嗪-3,5(2 H , 4 H )-二酮类化合物-triazine-3,5(2 H , 4 H )-二酮和醚，具有广泛的官能团耐受性。本次改造采用廉价低毒的二叔-丁基蒽醌在室温下作为无金属光催化剂和空气作为绿色氧化剂。此外，这种反应也可以由作为清洁能源的阳光驱动。该方法的合成效用通过克级反应和在生物活性分子关键中间体制备中的应用得到进一步证明。
