[EN] N-HYDROXYLSULFONAMIDE DERIVATIVES AS NEW PHYSIOLOGICALLY USEFUL NITROXYL DONORS [FR] DÉRIVÉS DE N-HYDROXYLSULFONAMIDE UTILISÉS COMME NOUVEAUX DONNEURS DE NITROXYLE PHYSIOLOGIQUEMENT UTILES
磺酰氯不仅在保护基团化学中发挥着至关重要的作用,而且还是磺酰胺合成中的重要起始原料,而磺酰胺是药物发现化学中急需的基序。尽管磺酰氯很重要,但不同合成方法的数量有限,其中大多数依赖于硫醇前体的传统氧化氯化化学。在本报告中,我们公开了一种在 HCl 和 Cu 催化剂存在下,由原料苯胺和 DABSO(用作稳定的 SO 2替代物)进行的新型桑德迈尔型磺酰氯合成方法。该方法适用于多种苯胺,并允许在水性后处理后分离磺酰氯,或在桑德迈尔反应完成后通过简单添加胺将磺酰氯直接转化为磺酰胺。该方法的可扩展性在 20 g 规模上得到了证明,并且以 80% 的产率和优异的纯度分离出相应的杂环磺酰氯。

The invention relates to N-hydroxylsulfonamide derivatives that donate nitroxyl (HNO) under physiological conditions and are useful in treating and/or preventing the onset and/or development of diseases or conditions that are responsive to nitroxyl therapy, including heart failure and ischemia/reperfusion injury. Novel N-hydroxylsulfonamide derivatives release NHO at a controlled rate under physiological conditions, and the rate of HNO release is modulated by varying the nature and location of functional groups on the N-hydroxylsulfonamide derivatives.
