摘      要：1、2－O－Isopropylidene－3－C－cyano－5－O－benzoyl－α－D－xylose 2 was preparedstereoselectively from 1，2－O－isopropylidene－3－oxo－5－O－benzoyl－α－D－xylose *** structure of 2was studied by two－dimensional NMR spectroscopy in conjunction with X－ray crystallography of itscorresponding 5－phenyl－1，2，4－oxadiazole isocarbonucleoside derivative 3． The absoluteconfigurations of 2 and 3，and conformation of 3 are described herein．
