2-Acetyl­amino-1,3,4,6-tetra-O-(tri­methyl­silyl)-2-de­oxy-α-d-gluco­pyran­ose

The title compound, C(20)H(47)NO(6)Si(4), was synthesized by per-O-tri­methyl­silylation of N-acetyl-d-glucosa­mine using chloro­tri­methyl­silane in the presence of hexa­methyl­disiloxane. The tri­methyl­silyl group and acetamido group are located on the same side of the pyran ring, showing an α-configuration glycoside. One of the tri­methyl­silyl groups is disordered over two orientations, with site-occupancy factors of 0.625 (9) and 0.375 (9). In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into supra­molecular chains along the a-axis direction.
