摘要

Synthesis of methyl 3-azido-2,3-dideoxy-4,6-di-O-p-tolylsulfonyl- and -6-O-p-tolylsulfonyl-脦脦-d-xylo-hexopyranosides is presented. High-resolution ¹H and ¹³C NMR spectral data for both compounds and their precursors, and the single-crystal X-ray diffraction analysis for methyl 3-azido-2,3-dideoxy-4,6-di-O-p-tolylsulfonyl-脦脦-d-xylo-hexopyranoside are reported. The influence of the O-protective group on the chemical shift of adjacent atoms in the ¹H and ¹³C NMR spectra is discussed.
