Abstract: | Standard chemical methods involving the use of O-acetylated glycosyl trichloroacetimidates as glycosylating agents were used to prepare the five 1,3-dideoxynojirimycin-3-yl beta-(1-->3)-linked oligo-glucosides (1-5) and also the beta-(1-->6)-bonded glucobiose (gentiobiose)-based analogue 6 as potential fungicides. In the course of the work, the beta-(1-->6), beta-(1-->6)-linked analogue 8 of 6 and 6-O- and 4-O-beta-glucopyranosyl-deoxynojirimycins 7 and 9, respectively, were also produced. |
