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.

Some azido and amino inositolderivatives were synthesised from l-quebrachitol. The reaction between the mesylated compound and sodium azide was studied experimentally. Ab initio quantum mechanical calculations were carried out for this process to better understand the reaction mechanism.

1D-3,4-Dideoxyphosphatidylinositol ether lipid 2, a PI analog, was synthesized through a sequence of protection/deprotection protocols and two Barton deoxygenation reactions, starting from L-(-)-quebrachitol. DDPIEL is 18-fold more potent than its monodeoxy counterpart DPIEL in the inhibition of P13-K. (C) 2000 Published by Elsevier Science Ltd.
