2,3-Di-O-benzoyl-1-O-p-nitrophenyl-6-O-pivaloyl-4-O-(3',4',6'-tri-O-acetyl-2'-deoxy-2'-N-phthalimido-beta-D-1'-glucopyranosyl)-beta-D-glucopyranose

The title compound, C51H50N2O20, is an intermediate in the synthesis of a substrate to be used in enzymological studies of lysozyme. It was synthesized via a trichloroacetimidate coupling of 2,3,6-tri-O-acetyl-2-deoxy-2-N-phthalimido-1-trichloroacetimidate-beta-D-glucopyranoside and p-nitrophenyl 2,3-di-O-benzoyl-6-O-pivaloyl-beta-D-glucopyranoside. Both glucose rings adopt chair conformations with one described as C-1(4) and the other as C-5(3). Atoms C1 and C4 are at distances of 0.727 (4) and -0.652(4) Angstrom, respectively, and O5' and C3' are at distances of 0.713 (4) and -0.555 (5) Angstrom, respectively, from their chair planes.
