报道了一种通过芳基亚磺酸盐和硝基芳烃的还原偶联组装(杂)芳基磺酰胺的方法。使用超声波浴开发了在 DMSO 中使用亚硫酸氢钠以及含或不含氯化锡 (II) 的各种还原条件,以改善反应均匀性和混合。制备了一系列带有精选官能团的(杂)芳基磺酰胺,并研究了转化机制。这些研究使我们提出了亚硝基芳烃中间体的形成,这是通过独立的分子偶联策略建立的。
In search of new ALS inhibitors without the previous knowledge of receptor crystal structure, DISCO module was applied to produce 3D-pharmacophore models, which provided information to design novel molecules by 3D-database searching. Then a number of molecules were synthesized. Several of them have some ALS inhibitory activities. (C) 1999 Elsevier Science Ltd. All rights reserved.
