-(3,6-Anhydro-2-deoxy-alpha-D-glucofurano)pyridine (2a), N-(o-phenylen
e)-2-deoxy-alpha-D-allofuranosylamine (4) and ydro-1-deoxy-D-arabino-p
entitol-1-yl)benzimidazole (8) were synthesized by reaction of 2-amino
pyridine or o-phenylenediamine with 3,6-anhydro-2-deoxy-D-glucose. For
mation of compound (4) is explained through a Michael-type addition of
the o-phenylenediamine on the intermediate alpha,beta-unsaturated car
bohydrate aldehyde (7).
