Abstract
6-O-Acetyl-3,4-di-O-benzyl-2-deoxy-2-p-methoxybenzylideneamino-d-glucopy ranosyl chloride, 3,4,6-tri-O-acetyl-2-deoxy-2-p-methoxybenzylideneamino-α-d-glucopy ranosyl bromide, 3,4,6-tri-O-acetyl-2-deoxy-2-p-methoxybenzylideneamino-α- and -β-d-glucopyranosyl trichloroacetimidate, and 3,4,6-tri-O-acetyl-2-deoxy-2-p-nitrobenzylideneamino-α-d-glucopyra nosyl 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. © 1990.File in questo prodotto:
