derivatives was synthesized in order to serve as model compounds for the analysis of the stereochemistry, regiochemistry, and defect structures of poly(vinyl glycoside)s. 13C NMR spectroscopic analysis of these compounds revealed that the attached chiral carbohydrate substituents induced a strong correlation of the chemicalshifts of both the anomeric C and the α-C atom of the aglycon with the absolute configuration
