properties in terms of carboxylatebinding were studied by means of NMR in DMSO‐d 6. The reported bambusurils bind selected chiral carboxylates with enantioselectivity factors up to 3.1. The results indicated that the selectivity towards different carboxylates is governed by the steric constraint of the substituents surrounding bambusuril portals. No clear trend in the binding affinities and their
氨苄青霉素是一类具有显着阴离子识别特性的大环阴离子受体,能够与各种无机阴离子以及羧酸盐或磺酸盐结合。最近,我们报道了使用非功能化手性bambusuril衍生物对手性羧酸酯的对映选择性识别。本文中,我们报道了两个新的具有酯官能团的手性bambusuril大环代表化合物的合成和客体特性,它们之间的取代基不同。通过DMSO- d 6中的NMR研究了它们在羧酸盐结合方面的超分子特性。报道的樟脑丸以高达3.1的对映选择性因子结合选择的手性羧酸盐。结果表明,对不同羧酸盐的选择性受孟买素门户周围的取代基的空间约束所支配。没有发现结合亲和力及其对映选择性的明显趋势。

paper, tert‑butyl (R)-(1-(4-(4-amino-1H-pyrrolo [3,2-c]pyridine-1-carbonyl) phenyl)ethyl)carbamate was designed and synthesized using 5-azaindoles as the core structure. The target compound was characterized by MS, NMR and IR, respectively. The crystalstructure of the target compound was determined by X-ray diffraction, and then the optimized crystalstructure was determined by DFT calculation using
