Autor: S. F. Jenkinson, D. Best, F. X. Wilson, G. W. J. Fleet, D. J. Watkin

Publikováno v: Acta Crystallographica Section E, Vol 66, Iss 4, Pp o853-o853 (2010)

The crystal structure of the title compound, C12H18N2O8, exists as O—H...O hydrogen-bonded layers of molecules running parallel to the ab plane. Each molecule is a donor and acceptor for six hydrogen bonds. The absolute stereochemistry was determin

1-(1-Carboxymethyl-1,4-anhydro-2,3-O-isopropylidene-α-d-erythrofuranosyl)thymine

Autor: G. M. J. Lenagh-Snow, S. F. Jenkinson, A. J. Stewart, G. W. J. Fleet, D. J. Watkin

Publikováno v: Acta Crystallographica Section E, Vol 66, Iss 2, Pp o404-o404 (2010)

X-Ray crystallography unequivocally determined the stereochemistry of the thymine base in the title compound, C14H18N2O7. The absolute stereochemistry was determined from the use of d-ribose as the starting material. There are two independent molecul

3,4-O-Isopropylidene-2-C-methyl-d-galactonolactone

Autor: N. Dai, S. F. Jenkinson, G. W. J. Fleet, D. J. Watkin

Publikováno v: Acta Crystallographica Section E, Vol 66, Iss 2, Pp o406-o407 (2010)

X-ray crystallography unequivocally confirmed the stereochemistry of the 2-C-methyl group in the title molecule, C10H16O6, in which the 1,5-lactone ring exists in a boat conformation. The use of d-galactose in the synthesis determined the absolute st
