The title compound, C35H31NO3, was obtained by the reaction of (S)-benzyl 2-amino-3-(4-hydroxyphenyl)propanoate and (chloromethanetriyl)tribenzene. The enantiomer has been assigned by reference to an unchanging chiral centre in the synthetic procedure. In the crystal, molecules are linked into chains running along the a axis by intermolecular O—H⋯O hydrogen bonds.

To a solution of (S)-benzyl 2-amino-3-(4-hydroxyphenyl)propanoate (0.68 g, 2.5 mmol), and (chloromethanetriyl)tribenzene (0.70 g, 2.5 mmol) in acetonitrile (8 ml) at 273 K was added dropwise triethylamine (0.40 g, 4 mmol). The cooling bath was removed and the mixture warmed to ambient temperature for 2 h. The solvent was removed and the crude product was purified by
(petroleum ether-ethyl acetate, 4:1) to give the title compound (I) as a white solid in 85% yield. Single crystals of (I) were obtained by slow evaporation of a petroleum ether/ethyl acetate solution (6:1 v/v).The NH hydrogen atom was located in a difference Fourier map and freely refined. All other H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.93 Å (aromatic), 0.97 Å (methylene), 0.98 Å (methine), O—H = 0.82 Å, and Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O). In the absence of significant
effects, Friedel pairs were merged. The of (I) was assigned assuming that the of the starting materials was retained during the synthesis.Data collection: CrystalClear (Rigaku, 2000); cell

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

The title compound is an important intermediate in the synthesis of isodityrosine, which occurs in plant cell wall proteins and presumably conveys a strengthening and/or defensive role to the proteins (Skaff et al., 2005). The molecular structure of the title compound is shown in Fig. 1. The bond lengths and angles in the compound are comparable to those reported for a similar compound (Luo et al., 2009). The dihedral angle between the C18-phenyl and C24-phenyl, C18-phenyl and C30-phenyl, C24-phenyl and C30-phenyl planes are 80.2 (1), 61.9 (1) and 65.4 (1)°, respectively. The crystal packing is stabilized by strong O—H···O intermolecular hydrogen-bonding interactions involving the hydroxyl group which link the molecules into a chain running along the a axis (Table 1).
