transporters based on a CyPLOS (cyclic phosphate-linked oligosaccharide) backbone, we describe the synthesis of a novel azido-derivatized CyPLOS analogue that is tailored for practical post-synthetic functionalization with a variety of labels. As a prerequisite for the effective preparation of this phosphate-linked macrocycle, the compatibility of azido alcohols as coupling agents in phosphoramidite
为了制备基于 CyPLOS(环状磷酸连接寡糖)骨架的离子转运蛋白库,我们描述了一种新型叠氮衍生的 CyPLOS 类似物的合成,该类似物专为具有各种标签的实际合成后功能化而量身定制。作为有效制备这种磷酸盐连接的大环的先决条件,通过使用 31 P NMR 光谱监测核苷 3'-亚磷酰胺与合适的标准偶联剂,在溶液中初步研究了叠氮醇作为亚磷酰胺合成方案中偶联剂的相容性。模型醇和叠氮化物。
