✦ Synopsis


ABSTRACf Previously unknown methyl 2,3-diacetamido-2,3-dideoxy-a-D-hexopyranosides having the gulo, allo, galacto, ido, and altro configurations, as well as 2,3-diacetamido-2,3-dideoxy-D-galactose, have been synthesised. 13C-N.m.r. data for all eight methyl 2,3-diacetamido-2,3-dideoxy-cu-D-hexopyranosides and for three 2,3-diacetamido-2,3-dideoxy-D-hexoses having the gluco, manno, and galacto configurations are reported. The regularity of changes in the spectra of 2,3diacetamido sugars, as compared with those of the parent hexoses, and the calculation of '"C-n.m.r.

spectra of their derivatives, using a method of additive corrections, are discussed.
