Structural Variations of N-Acetylneuraminic Acid, 14. Synthesis of the &β-Methyl Ketosides of 4-oxo-, 7-oxo-, and 8-oxo-N-Acetylneuraminic Acid and the Corresponding 7,7- and 8,8-Dimethoxy Derivatives Their Behaviour Towards CMP-Sialate Synthase

The 4-, 7-, and 8-oxo-sialic acid β-methyl ketosides 7, 10a, and 11a were obtained by transformation of easily available derivatives of N-acetylneuraminic acid (1a).The carbonyl migration from C-7 to C-8 can be carried out under well-defined conditions wi
