the regioselective synthesis of a 1‐(hetero)aryl‐3‐substituted tetrahydroindazolone library. The condensation of in situ generated arylhydrazine on solid supports with 2‐acylcyclohexane‐1,3‐diones ensured the efficiency of solid‐phase parallel synthesis. In addition, we introduced three unique core skeletons containing nitrophenyl, anilyl, and pyridyl groups to maximize the molecular diversity through
我们为1-(杂)芳基-3-取代的四氢吲哚并隆文库的区域选择性合成开发了一种实用的策略。原位生成的芳基肼在固体载体上与2-酰基环己烷-1,3-二酮的缩合确保了固相平行合成的效率。此外,我们引入了三个独特的核心骨架,其中包含硝基苯基,苯甲酰基和吡啶基,以通过在3D化学空间中极性表面的多样化显示来最大化分子多样性。无需进一步纯化即可构建平均纯度为92%的162元药物样四氢吲哚酮文库。
