Abstract

Abstract The synthesis of «reversed» 1, 3, 4‐oxadiazolyl C‐nucleosides by treatment of alduronic chlorides with N‐benzoylamino‐triphenylphosphinimine or by oxidation of aldehydo dialdose benzoylphenylhydrazones is described. One of these compounds is the first example of an «reversed» C‐amino‐nucleoside having a β‐heteroaryl‐ethylamino grouping, a structural unit whose introduction into a sugar molecule is interesting from a pharmacological standpoint.
