  摘要：

  3-酰基吡咯并[ 2,1- c ] [1,4]苯并恶嗪-1,2,4-三酮与硫代碳酰肼反应生成4-氨基-6-（酰基甲基）-3-亚磺酰基-3,4-二氢的混合物-1,2,4-三嗪-5（2 H）-ones和6-取代的1,4-苯并恶嗪-2,3-二酮可以通过分级结晶直接从反应混合物中分离出来。该反应可能涉及亲核转化的序列，中间形成螺[吡咯-2,6'-[1,2,4]三嗪]，该中间体经历C 2 -N 1的裂解在吡咯环上键合。通过X射线分析确定产物的结构，并通过UPLC / MS鉴定中间产物。1,2,4-三嗪衍生物也可以独立地与2,4-二氧代丁酸烷基酯或2-氧代丁二酸和硫代碳酰肼合成。由4-芳基-2,4-二氧代丁酸和硫代碳酰肼合成4-氨基-1,2,4-三嗪的已知程序已得到改进，以满足“绿色化学”原理。开发了两种合成取代的4-氨基-1,2,4-三嗪的新方法。所获得的化合物引起了药物化学，药理学和精细有机合成的兴趣。

  Treatment of 3,(5)-(di)chloro-2H-1,4-(benz)oxazin-2-ones with diazo compounds or sodium azide yields bi(tri)cyclic compounds which can be converted into [1,2,3]triazoles or 1,5-disubstituted tetrazoles via reactions with nucleophiles as methanol, water and amines.

  This study examines in depth benzoxazine nucleus for antimycobacterial property. We synthesized some benzoxazin-2-one and benzoxazin-3-one derivatives, which were tested for activity against a panel of Mycobacterium tuberculosis (Mtb) strains, including H37Ra, H37Rv and some resistant strains. Several compounds displayed a high antimycobacterial activity and the three isoniazid analogue derivatives 8a-c exhibited a MIC range of 0.125-0.250 mu g/mL (0.37-0.75 mu M) against strain H37Ra, therefore lower than the isoniazid reference drug. Two benzoxazin-2-one derivatives, 1c and 5j, together with isoniazid-analogue compound 8a, also revealed low MIC values against resistant strains and proved highly selective for mycobacterial cells, compared to mammalian Vero cells. To predict whether molecule 8a is able to interact with the active site of InhA, we docked it into the crystal structure; indeed, during the molecular dynamic simulation the compound never left the protein pocket. The more active compounds were predicted for ADME properties and all proved to be potentially orally active in humans.
• [1,4]Benzoxazine-2,3-diones as antiallergic agents

  The synthesis of a series of [1,4]benzoxazine-2,3-diones and a new class of compounds, benzobisoxazinetetrones, is described. These compounds were evaluated for their effect in the rat mast cell (RMC) test passively sensitized in vitro with rat antiovalbumin serum and for their effect in inhibitory passive cutaneous anaphylaxis (PCA) in the rat. Some of these compounds are of the same potency level as disodium cromglycate in the RMC test and some are effective orally in PCA.
