چکیده
The crystal structure unequivocally confirms the relative stereochemistry of the title compound, C(6)H(13)FO(5) [6-de-oxy-6-fluoro-d-galactitol or (2S,3R,4R,5S)-6-fluoro-hexane-1,2,3,4,5-penta-ol]. The absolute stereochemistry was determined from the use of d-galactose as the starting material. In the crystal, the molecules are linked by O-H⋯O and O-H⋯F hydrogen bonds, forming a three-dimensional network with each mol-ecule acting as a donor and acceptor for five hydrogen bonds.

Although 6-azido-6-de-oxy-l-galactose in aqueous solution is in equilibrium between the open-chain, furan-ose and pyran-ose forms, it crystallizes solely as 6-azido-6-de-oxy-α-l-galactopyran-ose monohydrate, C(6)H(11)N(3)O(5)·H(2)O, with the six-membered ring adopting a chair conformation. The structure exists as hydrogen-bonded chains, with each mol-ecule acting as a donor and acceptor of five...
متن کاملEnantioselective oxidation of galactitol 1-phosphate by galactitol-1-phosphate 5-dehydrogenase from Escherichia coli.
Galactitol-1-phosphate 5-dehydrogenase (GPDH) is a polyol dehydrogenase that belongs to the medium-chain dehydrogenase/reductase (MDR) superfamily. It catalyses the Zn(2+)- and NAD(+)-dependent stereoselective dehydrogenation of L-galactitol 1-phosphate to D-tagatose 6-phosphate. Here, three crystal structures of GPDH from Escherichia coli are reported: that of the open state of GPDH with Zn(2+...
