Investigated are AlCl3 and NaI catalyzed chemoselective demethylation reactions of methylethers of partly protected inositol derivatives, reactions which are greatly promoted by vicinal OH group and proceed in preference to the cleavage of the cis cyclohexylidene moiety.

A modified synthesis of 1L-1,2:3,4-di-O-cyclohexylidene-5-O-methyl-chiro-inositol has been accomplished that improves the overall procedure, yield, and environmental aspects of its formation. Several inositol analogues have been prepared from this intermediate for testing as biosynthetic inhibitors of glycosyl-phosphatidylinositol (GPI) anchor formation.
