    The D-3-phosphorylated myo-inositol phospholipids PtdIns(3)P, PtdIns(3,4)P-2, PtdIns(3,4,5)P-3 and Ptdins(3,5)P-2 were synthesised from myo-inositol orthoformate 8. Key transformations included the regioselective DIBAL- and trimethylaluminium-mediated cleavages of myo-inositol orthoformate intermediates and a resolution-protection protocol using the camphor acetals 17. The final reductive debenzylation was effected with Pearlman's catalyst [Pd(OH)(2)] in the presence of sodium hydrogen carbonate. The biological properties of the phospholipids were evaluated against various protein kinases (PKB and PDK-1) in which they played an important activation role.
