## Abstract The reaction of peracetylated __N__‐acetylneuraminic acid methyl ester 1 with nitrosyl acetate affords a mixture of __anti__/__syn__‐__N__‐nitroso derivatives 2a and 2aβ€², which can be transformed with sodium trifluoroethanolate into the 5‐diazo compound 3. The reaction of 3 with tetrabu
