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.
