Abstract Methyl l -sibirosaminide and N -acylkansosamine were synthesized via the same intermediate, methyl 4-amino-4,6-dideoxy-2,3- O -isopropylidene-3- C -methyl-α- l -mannopyranoside ( 7 ), from l -rhamnose in 7 and 10 steps, respectively. Conversion of 7 into the title compounds was performed by N -methylation or N -(2-methoxypropanoyl)ation followed by appropriate derivatization.
