摘要
The title compound 3 has been synthesized from 3,4, 6-tri-O-acetyl-2-deoxy-2-nitroso-alpha-D-glucopyranosyl chloride (1) via compound 2. Azide reduction of 3 is accompanied by O-->N-acetyl migration to afford N-acetyl-N- (3, 4, 6-tri-O-acetyl-2-deoxy-2-hydroxyimino-beta-D-arabino-hexopyranosyl)amine (4) , also characterized as its Z and E peracetates. on the basis of IR, H-1 NMR and X-ray structural data from compound 4, its beta-NHAc configuration, (Z) 2-hydroxyimino, and degrees-S2 conformation, were established.
