Na2S2O5 and nitro compounds in a DeepEutecticSolvent (DES) as a reaction medium is described. Thus, triarylbismuthines are used as reagents for the incorporation of SO2 into organic motifs. The bismuth salts formed as by-products can be easily removed from the crude reaction mixture by precipitation with water, while the use of volatile organic compounds (VOCs) as solvents can be avoided in the entire
描述了一种在深度共晶溶剂(DES)中使用铜催化的方法从三芳基双变异蛋白,Na 2 S 2 O 5和硝基化合物开始可持续合成磺酰胺的方法。因此,将三芳基双突变蛋白用作掺入SO 2的试剂变成有机图案。通过用水沉淀,可以很容易地从粗反应混合物中除去作为副产物形成的铋盐,同时在整个过程中可以避免使用挥发性有机化合物(VOC)作为溶剂。用作溶剂的低共熔混合物已得到充分表征,初步结果证明其毒性低。设计的DES还可以进行新颖的多组分反应,从而节省时间并减少纯化步骤,能源和成本。

In this study, synthesis of nine N-phenylsulfonamide derivatives was designed by starting from aniline, which is the simplest aromatic amine. These compounds were obtained in yields between 69 and 95%. Inhibitory properties of synthesized compounds on carbonic anhydrase I (CA I), CA II isoenzymes, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes were investigated. Inhibitors of

This invention pertains generally to the field of therapeutic compounds, and more particularly, to certain bicyclosulfonyl acid (BCSA) compounds which act as inhibitors of Tumour Necrosis Factor-α Converting Enzyme (TACE). The compounds are useful in the treatment of conditions mediated by TNF-α, such as rheumatoid arthritis; inflammation; psoriasis; septic shock; graft rejection; cachexia; anorexia; congestive heart failure; post ischaemic reperfusion injury; inflammatory disease of the central nervous system; inflammatory bowel disease; insulin resistance; HIV infection; cancer; chronic obstructive pulmonary disease (COPD); and asthma. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, in the inhibition of TACE, and in the treatment of conditions that are ameliorated by the inhibition of TACE.
Practical chemoselective aromatic substitution: the synthesis of <i>N</i>-(4-halo-2-nitrophenyl)benzenesulfonamide through the efficient nitration and halogenation of <i>N</i>-phenylbenzenesulfonamide
the metal-promoted tandem nitration and halogenation of N-phenylbenzenesulfonamide to synthesize N-(4-halo-2-nitrophenyl)benzenesulfonamide derivatives has been developed. The method shows highly practical chemoselective and functional group compatibility. In addition, it employs insensitive and inexpensive Cu(NO3)2·3H2O, Fe(NO3)3·9H2O, and NH4NO3 as the nitrationreagents, and it provides a direct
