Abstract
The detailed structure of methyl 4-acetamido-4-cyano-4,6-dideoxy-2,3-O-isop ropylidene-beta-D-allopyranoside was established by X-ray analysis confirmi ng allo configuration at C-4 and suggesting a C-4(1) conformation of the py ranose ring. The values of relevant torsion angles and calculated puckering parameters revealed a distortion into the direction of H-0(5), thus indica ting a flattening at C-1 and C-4.
