Coupling of 1,2-diradyl-sn-glycerol 5 with the novel inositol H-phosph
onate derivative, -O-benzyl-2,3:4,5-di-O-isopropylidene-myo-inositol H
-phosphonate (3), gave fluorescent analogs of phosphatidylinositol (Pt
dIns, 1) and PtdIns(4,5)-bisphosphate (PtdIns(4,5)P-2, 2). Unlike the
corresponding phosphoramidate, 3 was stable at -20 degrees C for sever
al months, making it a useful intermediate for the synthesis of myo-in
ositol phospholipids. (C) 1998 Elsevier Science Ltd. All rights reserv
