Abstract

4‐C‐glycosylthiazoles have been prepared by reacting thiourea or thioacetamide with a 6‐S‐benzyl‐6‐chloro‐1,2‐O‐isopropylidene‐3‐O‐methyl‐α‐D‐xylo‐6‐thiohexofuranos‐5‐ulose (7). The latter compound which constitutes an interesting synthetic intermediate in carbohydrate chemistry has been obtained by successive oxidation and chlorination of 6‐S‐benzyl‐1,2‐O‐isopropylidene‐3‐O‐methyl‐α‐D‐6‐thioglucofuranose.

## 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
