Distortion of the ring conformation in β-gluco- and β-xylopyranosides upon their per-O-sulfation was observed. In the case of glucose, a conformation intermediate between 3,OB and 3S1 was found, while complete 4C1→1C4 inversion was detected in xylopyranoside. The conformational changes were evidenced experimentally by measuring intra-ring 1H–1H coupling constants and nuclear Overhauser effect (NOE) and were additionally confirmed by ab initio calculations.
