scyllo-Inositol derived 1,2-trans-diequatorial halohydrins can be efficiently converted to the corresponding epoxides in the presence of lithium hydride. The structure of one of the epoxides was determined by single crystal X-ray diffraction analysis. This provides a potential route for the preparation of ring modified inositol derivatives. DFT calculations suggest that this epoxide formation could be

Tetra-O-alkyl ethers of 1,2-O-isopropylidene-myo-inositol are converted into 1,2,4-trialkoxybenzenes on treatment with potassium t-butoxide in dimethyl sulphoxide at 80°. An intermediate product in the conversion of 3,4,5,6-tetra-O-benzyl-1,2-O-isopropylidene-myo-inositol into 1,2,4-trisbenzyloxybenzene was isolated. The intermediate, 3,4,5,6-tetrakisbenzyloxycyclohex-2-enol, was converted into 4,5
