Abstract
The structure of methyl 4-amino-4-cyano-4,6-dideoxy-2,3-O-isopropylidene-al pha -L-talopyranoside was established by X-ray analysis confirming a tale c onfiguration at C-4 and suggesting a C-1(4) conformation of the pyranose ri ng. The values of relevant torsion angles and calculated puckering paramete rs revealed a distortion into the direction of E-5 conformation, thus indic ating a flattening at C-2.
