heal.abstract	The rotamers about the C(5)–C(6) bond of a series of 2,3,4-tri-O-acetyl-6-X-a-D-glucopyranozide derivatives resulting by substitution at C(6) or O(6) have been studies with1H-NMR spectroscopy (400 MHz) and X-ray structure analysis. The methyl 2,3,4-tri-O-acetyl-6-O-triphenylmethyl-a-D-glucopyranoside and the N-(I-O-methyl-2,3,4-tri-O-acetyl-a-D-glucopyranose-6-yl)-pyridinium nitrate crystallize in the P21 space group with a=14.940(1),b=11.232(1),c=9.0773(7), and ß=94.480(7) anda=7.670(1),b=15.384(3),c=9.624(1) and ß=104.90(1), respectively; the methyl 2,3,4-tri-O-acetyl-6-O-nitro-a-D-glucopyranoside and methyl 2,3,4-tri-O-acetyl-6-O-deoxy-6-iodo-a-D-glucopyrano-side crystallize in the	en
