## Abstract The orientation of the cycloaddition of diazomethane on unsaturated branchedchain sugars has been studied. For 3‐__C__‐cyanomethylidene‐3‐deoxy‐1,2‐__O__‐isopropylidene‐α‐D‐__glycero__‐tetrofuranose the orientation was ‘normal’ and did not depend on the configuration at the double bond.
