N-Fluoren-9-ylmethoxycarbonyl-protected sugar amino acids derived from α-O-methoxy- and 2,3-dehydroneuraminic acids have been prepared. Incorporation of these monomer units into solid-phase synthesis led to the efficient synthesis of two series of oligomers varying from one to eight units in length. The (1-5)-linked amides of 2,3-dehydroneuraminic acid were further subjected to hydrogenation giving a third series of oligomers with a β-hydrido substituent at the anomeric carbon.
