, p. 1881 - 1884 (2007/10/02)

Investigated are AlCl3 and NaI catalyzed chemoselective demethylation reactions of methyl ethers 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.
