• Synthesis of 1,4-benzothiazinones from acylpyruvic acids or furan-2,3-diones and <i>o</i>-aminothiophenol

  Two synthetic approaches to enaminones fused to 1,4-benzothiazin-2-one moiety, which can be interesting in studies on biological activity, chemosensors, and fluorescence, were developed via the reaction of furan-2,3-diones or acylpyruvic acids in the presence of carbodiimides with o-aminothiophenols. The target enaminones were formed together with pharmaceutically interesting 2-hydroxy-2H-1,4-benzothiazin-3(4H)-ones. A selective synthetic approach to 2-hydroxy-2H-1,4-benzothiazin-3(4H)-ones was developed via the solvent-switchable reaction of furan-2,3-diones with o-aminothiophenol. Preliminary biological assays (antimicrobial, acute toxicity) of the new compounds were carried out.

  通过呋喃-2,3-二酮或酰基丙酮酸在碳化二亚胺存在下与邻氨基苯硫酚的反应，我们开发了两种合成融合了 1,4-苯并噻嗪-2-酮分子的烯酰胺酮的方法，这些烯酰胺酮在生物活性、化学传感器和荧光研究方面具有重要意义。目标烯酮与具有药学意义的 2-羟基-2H-1,4-苯并噻嗪-3(4H)-酮一起形成。通过呋喃-2,3-二酮与邻氨基苯硫酚的溶剂切换反应，开发了一种 2-羟基-2H-1,4-苯并噻嗪-3(4H)-酮的选择性合成方法。对新化合物进行了初步的生物检测（抗菌、急性毒性）。

  Thermal reaction of aroylketenes 2 with cyclic enol ethers such as 2, 3-dihydrofuran (A), 2, 3-dihydropyran (B), 1-trimethylsilyloxycyclopentene (C), 1-trimethylsilyloxycyclohexene (D), 3-trimethylsilyloxyindene (E), and 4-trimethylsilyloxy-1, 2-dihydronaphalene (F) was carried out to investigate the reactivity of 2 with these olefins. The main reaction was Michael-type addition to give the 1, 3-diketones 3 and 9, and the 1, 3, 5-triketones 13, 15, 18, and 20, depending on the olefins used. The addition of the olefins was facilitated by introduction of a nitro or chloro group into the aryl part of 2 and was profoundly retarded by steric hindrance of the olefins

  芳酰基烯酮2与环状烯醇醚如2,3-二氢呋喃（A）、2,3-二氢吡喃（B）、1-三甲基硅氧基环戊烯（C）、1-三甲基硅氧基环己烯（D）、3-三甲基硅氧基茚（E）和4-三甲基硅氧基-1,2-二氢萘（F）的热反应被进行，以研究2与这些烯烃的反应性。主要反应是迈克尔型加成，产生1,3-二酮3和9以及1,3,5-三酮13、15、18和20，具体取决于所用的烯烃。烯烃的加入因2的芳基部分引入硝基或氯原子而得到促进，并因烯烃的空间位阻而显著减慢。

  The thermal addition reaction of various aroylketenes (C) generated by the thermolysis of 5-aryldioxofurans (A) to 1-aryl-1-trimethylsilyloxyethylenes gave 1, 5-diarylpentane-1, 3, 5-triones (D) and 2, 6-diaryl-4H-pyran-4-ones (E). The introduction of electron withdrawing substituents in the aroylketene and of electron donating substituents facilitated the addition reaction. The observed substituent effects and the reaction mechanism are interpreted in terms of molecular orbital analyses.
