## 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
