With the aim of preparing a library of ion 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 synthetic protocols was preliminarily investigated in solution by using 31 P NMR spectroscopy to monitor the standard coupling of a nucleoside 3′‐phosphoramidite with suitable model alcohols and azides.
