1H NMR spectroscopy for phosphorus containing hetero sugars (phospha sugars 9a-d and 17a-d) revealed the stereoisomeric configurations and the chair conformations for α - and β -1,2,4-tri-O-acetyl-3,5-di- deoxy-5-C-(isopropyl- and phenyl-phosphinyl)-D-erythro-pentopyranoses. The conformations of the title compounds were characterized as 4C 1 chair form in CDCl3 by 1H NMR (500 MHz), and the conformations were in accord with those in the solid state determined by X-ray crystallographic analyses.
Synthesis of 3'-deoxy-5'-S-ethyl-5'-thio-β-D-erythro- pentofuranosylthymine as potential antitumor agent

The title compound 6 was prepared from the key sugarintermediate 3- deoxy-1,2-o-isopropylidene-α-D-erythro-pentofuranosylthymine (1) via five steps. Alternatively, 6 was synthesized from the nucleoside 3'-deoxy-β-D- erythro-pentofuranosylthymine (7) in two steps.
THE SYNTHESIS OF (S) AND (R) ENANTIOMERS OF NOVEL HYDROXYMETHYLATED ISODIDEOXYNUCLEOSIDES

, p. 1853 - 1864 (2007/10/02)
Novel isomeric dideoxynucleosides, with symmetry introduced at the 2'-position (4'-position using normal nucleoside numbernig) through the introduction of an additional hydroxymethyl group, have been synthesized.Both (R) and (S) enantiomeric series were investigated.The methodologies developed have generality and the presence of the hydroxymethyl group trans to the base may be used to introduce a wide variety of functionalities at this position.
Chiral Buildung Units from Carbohydrates, IX. - Synthesis of Enantiomeric 2,8-Dimethyl-1,7-dioxaspiroundecan-4-ols, Components from the Pheromone Bouquet of Andrena wilkella
Redlich, Hartmut,Schneider, Bernd
, p. 412 - 424 (2007/10/02)
The enantiomeric spiro acetals 29 and 35 are synthesized via the open-chained compounds 27 and 33 which are obtained by connecting the open-chained, D- or L-threo configurated, blocked trideoxytrimethylene dithioacetals IV with 1-iodo-4-(tetrahydropyranoloxy)pentane (1).One of the two enantiomers 29 or 35 represents a component from the pheromone bouquet of Andrena wilkella.The synthesis of racemic 1 is described as well as the synthesis of 1 in optically pure form in two different, independent ways, starting from D-glyceraldehyde and D-glucose.
