The recognition capabilities of acyclic pyridine-based receptors toward monosaccharides were evaluated. Aminopyridine receptors based on the 2,4,6-trimethyl- or 2,4,6-triethylbenzene frame show high β vs α binding selectivity in the recognition of glucopyranosides. Amidopyridine receptors, which are sterically less hindered at nitrogen, display high efficiency and an inverse selectivity. The 2-aminopyridine
评估了基于无环吡啶的受体对单糖的识别能力。基于2,4,6-三甲基或2,4,6-三乙苯骨架的氨基吡啶受体在识别吡喃葡萄糖苷方面表现出高的β对α结合选择性。在氮上空间受阻较少的氨基吡啶受体显示出高效率和相反的选择性。已经建立了2-氨基吡啶基团作为单糖结合中的高效识别基团。影响受体的结合性能的因素1 - 15,这在本质上和用作建筑块结合和间隔物亚单位数目不同,进行了讨论。
