Article abstract of DOI:10.1016/0008-6215(90)84052-V

The acid-catalysed reactions of myo-inositol with 3-5 equiv. of 2-methoxypropene or 2,2-dimethoxypropane in methyl sulfoxide or N,N-dimethylformamide gave mixtures of the 1,2:4,5-, 1,2:5,6-, and 1,2:3,4-di-O-isopropylidene derivatives with little or none
