(Received 14 December 2011; accepted 22 February 2012; online 29 February 2012)

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).

Comment top

As part of a program to synthesize phosphatidylinositol phosphates for biological studies, the synthesis of phosphatidylinositol 4,5-bisphosphate was undertaken following a literature procedure (Kubiak & Bruzik, 2003). Crystals of an intermediate, the title compound (I), C56H68O15P2Si, were obtained from a hot EtOAc/petroleum ether (1:4) solution, after chromatographic purification.

The asymmetric unit of (I) contains one independent molecule of the title compound (Fig. 1). The absolute configuration of the molecule was indicated at low significance by anomalous dispersion effects and it confirmed the expected configuration.

One benzyloxy substituent (C28—C34) on atom P2 was disordered; only the major final model is shown in Figure 1. There is a wide variation in O–C (methylene) bond lengths (1.425 (7)–1.482 (7)) in the benzoyloxy chains but the average, and all other dimensions are consistent with previous reports of related compounds [CSD (Allen, 2002) codes TIXDUA (Sato et al., 2008) and MIHYOS (Bello et al., 2007)]. Crystal stabilization is provided by weak non-classical phenyl C–H···O and C–H···π interactions (Table 2, Cg1 is the centroid of ring C8–C13) building head to tail chains along the b axis. The key motifs (Bernstein et al., 1995) are C(14) and R22(28), the latter shown in Figure 2 involving the H32A···O10 interactions.

Experimental top

The title compound was prepared as described for compound 66 in Kubiak & Bruzik (2003). Crystals were obtained from a hot EtOAc/petroleum ether (1:4) solution after purification and isolation (mp: 368–369K). [α]20D = +7.3 (c 2.0 g 100 mL-1, CHCl3); 31P NMR (202 MHz, CDCl3) δ -1.4, -1.1; HRMS(ESI) calcd for C56H68NaO15P2Si [M+Na] 1093.3700, found 1093.3712

Refinement top

Refinement of the final model gave conventional R (R1) of 12% with many data having Fo >> Fc. This was consistent with overlap of data given the (unexpectedly large) length of the c axis, and the initial difficulty in defining the unit cell for data processing. It was not possible to recollect data using more suitable diffractometer settings or radiation wavelength. Data with I(obs) > x*I(calc) and with I(obs)-I(calc) > x*Sigma(Iobs) were removed from the dataset, progessively from x 2.0 to x=1.3. Using the remaining 8053 data from an x value of 1.45 gave a "worst agreement" table which indicated that most of the overlapped data had been removed: the 1977 reflections removed gave an R1 of 0.36. In refinement, 10 further reflections measured at low theta angle with I(obs) << I(calc) were removed as outliers.

The phenyl ring atoms C29—C34 (Figure 1) were disordered over two orientations dictated by the two-site disorder of C28. The two corresponding phenyl ring atom sets were located and refined with a total occupancy of 1.0 with each having a group and individual C–C distance constraint (AFIX 6 & DFIX) of 1.39 Å. All carbon atoms were given a common isotropic Uisod value and hydrogen atoms were added at expected positions with fixed U values of 1.5*Uisod. The C–H distances for the two C28 sites were refined with a C—H restraint of 0.99 (3) Å. Final group occupancies were 0.649 (7):0.351 (7) and the common carbon U was 0.0510 (11) Å2. All other carbon-bound H atoms were constrained to their expected geometries [C—H 0.95,0.98, 0.99 Å]. All methyl H atoms were free to rotate (HFIX 137). All methyl & disordered H/other H atoms were refined with Uiso 1.5/1.2 times the Ueq of their parent atom. All other non-hydrogen atoms were refined with anisotropic thermal parameters.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
