adopted for lead generation in the pharmaceutical industry. However, fragment screening collections are often predominantly populated with flat, 2D molecules. Herein, we report the synthesis of piperidine-based 3D fragment building blocks – 20 regio- and diastereoisomers of methyl substituted pipecolinates using simple and general synthetic methods. cis-Piperidines, accessed through a pyridine hydrogenation
基于片段的药物发现现在被广泛用于制药行业的潜在客户开发。然而,片段筛选集合通常主要由平面二维分子组成。在此,我们报告了基于哌啶的 3D 片段构建块的合成——20 种甲基取代的哌啶甲酸酯的区域异构体和非对映异构体,使用简单和通用的合成方法。使用构象控制和统一的反应条件,将通过吡啶氢化获得的顺式-哌啶转化为它们的反式-非对映异构体。此外,非对映选择性锂化/俘获用于获得反式哌啶。从 20顺式衍生的虚拟片段库的分析- 和反式二取代哌啶表明它由具有适合分子特性的 3D 分子组成,可用于基于片段的药物发现程序。
