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 group of 2-mercaptobenzo-[d]-imidazole, whereas in the solid-phase case, Merrifield resin was introduced at an internal amine group of benzo-[d]-imidazole. To afford the desired 2-alkoxy/thioalkoxy benzo-[d]-imidazole analogues, we used various alkyl halides, alcohols, and thiols in solution phase, and to obtain 2-thione benzo-[d]-imidazole derivatives on solid phase, we used diverse alkyl halides and boronic acids. Finally, to measure the drug potential to be orally active and the molecular diversity in three-dimensional (3D) space, we calculated physicochemical properties and displayed energy-minimized 3D structures. As a result, the libraries from solution phase and solid phase show distinct features in physicochemical properties and skeletal diversities in 3D space.

的2-烷氧基/硫代烷氧基苯并[合成d -2-硫酮]咪唑和苯并[ d ]咪唑经由基于相，化学选择性反应

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 ]-咪唑的硫醇基反应，而在固相情况下，将Merrifield树脂引入到苯并-[ d ]-咪唑的内部胺基上。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，我们使用了多种烷基卤和硼酸。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空间中的物理化学特性和骨骼多样性方面显示出独特的特征。
