Abstract: The detailed structure of methyl 4-acetamido-4-cyano-4,6-dideoxy-2,3-Oisopropylidene-ß-D-allopyranoside was established by X-ray analysis confirming allo configuration at C-4 and suggesting a ⁴C₁ conformation of the pyranose ring. The values of relevant torsion angles and calculated puckering parameters revealed a distortion into the direction of ⁰H₅, thus indicating a flattening at C-1 and C-4.

Keywords: Amino nitrile; methyl allopyranoside; amino sugar; X-ray analysis
