1D-1-O-tert-Butyl­diphenyl­silyl-2,3,6-O-tris­(meth­oxy­methyl­ene)-myo-inositol 4,5-bis­(dibenzyl­phosphate)

The title compound [systematic name: tetra­benzyl (1R,2R,3S,4R,5R,6S)-4-(tert-butyl­diphenyl­sil­yloxy)-3,5,6-tris­(meth­oxy­meth­oxy)cyclo­hexane-1,2-diyl bis­phosphate], C₅₆H₆₈O₁₅P₂Si, was isolated as an inter­mediate in the preparation of a phosphatidylinositol phosphate for biological studies. In the crystal, the mol­ecules are connected via one methyl­ene C—H...π and two weak phen­yl–ether C—H...O inter­actions. One benz­yloxy group is disordered over two overlapping positions with an occupancy ratio of 0.649 (7):0.351 (7).
