A mild and effective one-pot synthesis of 1,2,3-benzotriazin-4(3H)-ones and benzothiatriazine-1,1(2H)-dioxide analogues has been developed. The method involves the diazotisation and subsequent cyclisation of 2-aminobenzamides and 2-aminobenzenesulfonamides via stable diazonium salts, prepared using a polymer-supported nitrite reagent and p-tosic acid. The transformation was compatible with a wide range
开发了一种温和有效的一锅法合成 1,2,3-benzotriazin-4(3 H )-ones 和 benzothiatriazine-1,1( 2H )-dioxide 类似物。该方法涉及通过使用聚合物负载的亚硝酸盐试剂和对甲苯磺酸制备的稳定的重氮盐对 2-氨基苯甲酰胺和 2-氨基苯磺酰胺进行重氮化和随后的环化。该转化与多种芳基官能团和酰胺/磺酰胺取代基相容,可用于合成药学上重要的靶标。通过制备含有 1,2,3-benzotriazin-4(3 H )-one的 α-氨基酸,进一步证明了一锅重氮环化过程的合成效用。
Design, Synthesis, and Potency of Pyruvate Dehydrogenase Complex E1 Inhibitors against Cyanobacteria
designed and synthesized. A part of 10, 17, and 21 displayed potent inhibition of Escherichia coli pyruvate dehydrogenase complex E1 (E. coli PDHc-E1) (IC50 = 2.12–18.06 μM) and good inhibition of Synechocystis sp. PCC 6803 (EC50 = 0.7–7.1 μM) and Microcystis sp. FACH 905 (EC50 = 3.7–7.6 μM). The algaecidal activity of these compounds positively correlated with their inhibition of E. coli PDHc-E1. In particular
Synthesis of 3-indolylmethyl substituted (pyrazolo/benzo)triazinone derivatives under Pd/Cu-catalysis: Identification of potent inhibitors of chorismate mutase (CM)
identification of potential antitubercular agents due to its absence in animals but not in bacteria. A series of 3-indolylmethyl substituted pyrazolotriazinone derivatives were designed and docked into CM in silico as potential inhibitors. These compounds were efficiently synthesized using the Pd/Cu-catalyzed coupling-cyclization in a single pot involving the construction of indole ring. The methodology

An expedientsynthesis of benzo[c][1,2]dithiol-3-ones via metal-free denitrogenative transannulation of benzotriazinones is developed, which represents the first example of acid-mediated heteroannulation of benzotriazinones. This newly discovered reactivity of benzotriazinones enables the streamline synthesis of diverse benzo[c][1,2]dithiol-3-ones in decent yields by using sodium sulfide as the sulfur
通过苯并三嗪酮的无金属脱氮环环化,开发了苯并[ c ][1,2]二硫醇-3-酮的便捷合成方法,这是酸介导苯并三嗪酮杂环化的第一个例子。这种新发现的苯并三嗪酮的反应活性使得通过使用硫化钠作为硫源在简单的反应条件下能够以良好的产率简化合成各种苯并[ c ][1,2]二硫醇-3-酮。
