2-Alkoxy/thioalkoxy benzo-[d]-imidazole and 2-thione benzo-[d]-imidazole libraries were constructed in solution phase and on solid phase, respectively. The key step in this work is the phase-based chemoselective reaction of the 2-mercaptobenzo-[d]-imidazole intermediate with benzyl chloride (solution phase) and Merrifield resin (solid phase). In the solution-phase case, benzyl chloride reacted with the thiol
分别在溶液相和固相上构建了2-烷氧基/硫代烷氧基苯并-[ d ]-咪唑和2-硫酮苯并-[ d ]-咪唑的文库。这项工作的关键步骤是2-巯基苯并-[ d ]-咪唑中间体与苄基氯(溶液相)和Merrifield树脂(固相)的基于相的化学选择性反应。在溶液相情况下,苄基氯与2-巯基苯并-[ d ]-咪唑的巯基反应,而在固相情况下,将Merrifield树脂引入苯并-[ d ]-咪唑的内部胺基。提供所需的2-烷氧基/硫代烷氧基苯并-[ d]-咪唑类似物,我们在溶液相中使用了各种烷基卤,醇和硫醇,在固相中获得了2-硫酮苯并-[ d ]-咪唑衍生物,我们使用了各种烷基卤和硼酸。最后,为了测量具有口服活性的药物潜力和三维(3D)空间中的分子多样性,我们计算了理化性质并显示了能量最小的3D结构。结果,来自溶液相和固相的库在3D空间中的物理化学性质和骨骼多样性方面显示出不同的特征。
