reaction is caused by endocycliccleavage of the pyranosides. Evidence for endocycliccleavage of conformationallyrestricted pyranosides in the chair form was obtained by intra‐ and intermolecular Friedel–Crafts reactions, chloride addition, and reduction of the generated cation. On the other hand, pyranosides with the distorted conformation were never cleaved in an endocyclic manner.
