title: N-p-methoxybenzylidene derivatives of 2-amino-2-deoxy-D-glucose as glycosyl donors: a reinvestigation.
abstract: 6-O-Acetyl-3,4-di-O-benzyl-2-deoxy-2-p-methoxybenzylideneamino-D- glucopyranosyl chloride, 3,4,6-tri-O-acetyl-2-deoxy-2-p-methoxybenzylideneamino-alpha-D-glu copyranosyl bromide, 3,4,6-tri-O-acetyl-2-deoxy-2-p-methoxybenzylideneamino-alpha- and -beta-D- glucopyranosyl trichloroacetimidate, and 3,4,6-tri-O-acetyl-2-deoxy-2-p-nitrobenzylideneamino-alpha-D-gluco pyranosyl bromide have been synthesised, and their behaviour as glycosylation agents with various soluble promoters has been investigated. The results obtained question the accepted non-participating character of the N-p-methoxybenzylideneamino group.
