glycosyl trichloroacetimidates as glycosylating agents were used to prepare the five 1,3-dideoxynojirimycin-3-yl β-(1→3)-linked oligo-glucosides ( 1 – 5) and also the β-(1→6)-bonded glucobiose (gentiobiose)-based analogue 6 as potential fungicides. In the course of the work, the β-(1→6), β-(1→6)-linked analogue 8 of 6 and 6- O - and 4- O -β-glucopyranosyl-deoxynojirimycins 7 and 9 , respectively, were also
