On the basis of the /sup 13/C NMR spectra it was shown that for reducing sugars equilibrium between ..cap alpha..- and ..beta..-pyranose forms is established in dioxane solution in the course of 0.5-1 h. The principle of the bicyclophosphorylation of mutarotating sugars, which takes into account the interconversions of the tautomeric forms of carbohydrates, is formulated. The /sup 31/P NMR spectra were determined in dioxane on a Varian CFT-80 spectrometer, external standard 85% H/sub 3/PO/sub 4/; /sup 13/C NMR spectra were determined on a Bruker 250 spectrometer, external standard TMS.
