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.

## Abstract The syntheses of three types of sugar nitrones (aldonitrone, ketonitrone and α‐β unsaturated aldonitrone) are described. On 1,3‐dipolar cycloaddition with phenylacetylene, the aldonitrone gave two Δ~4~‐isoxazolines epimeric at the new asymetric carbon, while the same reaction on the ket
