Chiral aliphaticamine compounds exhibit a range of physiological activities, making them highly sought-after in the pharmaceutical industry and biological research. One notable obstacle in studying these compounds stems from the pronounced steric hindrance surrounding the nitrogen atom. This characteristic often leads to a weak affinity of acyclic secondary amines for molecular probes, making their
手性脂肪胺化合物表现出一系列的生理活性,使其在制药工业和生物研究中备受追捧。研究这些化合物的一个显着障碍源于氮原子周围明显的空间位阻。这一特性通常导致无环仲胺对分子探针的亲和力较弱,使得它们的手性辨别变得复杂。为了应对这一挑战,我们的研究推出了一种新型19 F 标记探针,能够识别和区分这些无环仲胺的对映体。通过策略性地合并单个氟原子作为19 F 标记,我们成功地减少了结合位点的空间位阻。这种改变增强了探针对体积较大的分析物的亲和力。为了证明其有效性,我们已成功地将我们的探针用于相关药物的手性分析,准确地确定了它们的对映体组成。

computational study of a supramolecular balance to quantify ligand–ligand interactions in metal complexes and induce high heterocomplex preferences. Noncovalent interaction areas of flexible chiral phosphoramidite ligands are identified in palladium complexes with high conformational stability. The combined CH–π and π–π interactions reveal design patterns for binding and folding of chiral ligands and catalysts
