We applied a new synthetic method to C-disaccharides to obtain 2-deamino-tunicamine, the 2-hydroxy analogue of tunicamine, which is the main nucleus of tunicamycin antibiotics. 6-Deoxy-6-diazo-1:2,3:4-di-O-isopropylidene-D-galactopyranose was synthesized and reacted with methyl 2,3-O-isopropylidene-β-D-ribopentonodialdo-1,4-furanoside, to obtain a mixture of ketone and an epoxide with C-disaccharide
