N-trifluoroacetyl sialyl phosphite donors for the synthesis of α(2 → 9) oligosialic acids

(Chemical Equation Presented) A new method for the synthesis of α(2 → 9) oligosialic acids is developed using phosphite sialyl donors that are protected with a C-5 N-trifluoroacetyl (NHTFA) substituent. Compared with conventional donors, these donors gave a higher degree of α-anomeric selectivity during glycosidic bond formation and better yields during iterative sialylation in the synthesis of oligosialic acids.
