In this report, the first metal-free construction of primary sulfonamides through a direct three-componentreaction of sodium metabisulfite, sodium azide and aryldiazonium has been established. Readily available inorganic Na2S2O5 and NaN3 were applied as the sulfur dioxide surrogate and nitrogen source respectively. The widely used sulfonamide drugs Celecoxib and Sulpiride, which possess multiple heteroatoms
在该报告中,已经建立了通过亚硫酸氢钠,叠氮化钠和芳基重氮的直接三组分反应的伯磺酰胺的第一个无金属结构。分别将现成的无机Na 2 S 2 O 5和NaN 3分别用作二氧化硫的替代物和氮源。具有多个杂原子和含活性氢官能团的磺胺药物塞来昔布和舒必利有效地与–SO 2 NH 2一起安装小组在后期。对照实验和动力学研究表明,该转化涉及芳基,磺酰基和共轭膦亚胺基。
A novel series of benzoylsulfonamide derivatives were synthesized and biologically evaluated. Among them, 4-(biphenyl-4-ylmethylsulfanylmethyl)-N-(hexane-1-sulfonyl)benzamide (compound 18K) was identified as a proteintyrosinephosphatase 1B (PTP1B) inhibitor with potent and selective inhibitory activity against PTP1B (IC50=0.25 µM). Compound 18K functioned as a non-competitive inhibitor and bound
