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.
