## Abstract The peracetylated methyl ester 1 of Nβacetylneuraminic acid was transformed into the oxazoline derivative 2, which was hydrogenated with Pd/C/H~2~ to give the 4βdeoxyβNeu5Ac2en derivative 3. Acid cleavage of the oxazoline 2 by trifluoroacetic acid (THF) gave the 4βepiβNeu5Ac2en derivati
