Abstract
In both the title structures, O-ethyl N-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)thiocarbamate, C(17)H(25)NO(10)S, and O-methyl N-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)thiocarbamate, C(16)H(23)NO(10)S, the hexopyranosyl ring adopts the (4)C(1) conformation. All the ring substituents are in equatorial positions. The acetoxymethyl group is in a gauche-gauche conformation. The S atom is in a synperiplanar conformation, while the C-N-C-O linkage is antiperiplanar. N-H.O intermolecular hydrogen bonds link the molecules into infinite chains and these are connected by C-H.O interactions.
