organic compounds
The crystal structure of p-nitrophenyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside, C20H23NO12, was determined to ascertain its stereochemistry. The ring adopts a 3C5 chair conformation, with C3 and O5 atoms at distances of 0.60 (1) and −0.72 (1) Å, respectively, on opposite sides of the C1, C2, C4 and C5 plane. All substituents are in equatorial positions. The carbonyl bonds of the acetyl groups on C2, C3 and C4 are nearly coplanar with their respective ring C-H bonds and point in the same direction.
