The synthesis of 3-substituted l-fuco-azafagomines from d-lyxose is reported. They represent the first example of aza-C-glycosides having a biimino (-NH-NH-) moiety. The key step of the synthesis is the introduction of the hydrazine moiety by reductive hydrazination of a 1-deoxy-ketohexose with tert-butyl carbazate. Their glycosidase inhibitory properties are also reported.

aminomethyl C-3 substituted l-fuco-azafagomine and of its C-6 epimer from d-lyxose is reported. The key step of the synthesis is the introduction of the biimino (–NH–NH–) moiety by reductive hydrazination of a 1-deoxy-ketohexose with tert-butyl carbazate. The 3-aminomethyl-azafagomine derivatives were used as lead compounds in the generation of libraries of novel types of derivatives by attaching different
