Syntheses of methyl 2, 3-di-O-benzyl-5, 6-dideoxy-5, 6-epimino-α-L-altrofuranoside (4a) and 3-O-benzyl-5, 6-dideoxy-5, 6-epimino-1, 2-O-isopropylidene-β-L-idofuranose (11a) were described. It was found that an attack of nucleophiles in these epimines occurs exclusively in the terminal position with epimine ring opening.
