The pKa values of six amine‐linked pseudodisaccharides have been determined by using an NMR‐based titration method. The pKa varies significantly depending on the linkage position and is inversely correlated with the number of electronegative groups in the β‐position to the amino group. Four of the pseudodisaccharides contain α‐altroside moieties, the conformations of which were determined in the protonated...
