Comment

In recent years phosphono-peptides have stimulated a great deal of interest due to their considerable biological activities, including antigrowth (Li et al., 1999), antitumoral (Liu et al., 2002), antiviral (Wang et al., 2001), and inhibiton of serine protease effects (Senten et al., 2003 and Joossens et al., 2004).

The title compound crystallized with two independent chiral molecules (A and B) in the asymmetric unit (Fig. 1). They differ only in the chirality of atom C7 (molecule A) and C7' (molecule B).

In the crystal the two independent molecules are linked via N—H···O=P hydrogen bonds, involving the amide unit and a phosphoryl O atom, to form dimers (Table 1).

Experimental

To a solution of the starting material, tert-butyl (2S,3S)-1-((isopropoxy(isopropyl)phosphoryl)(phenyl)methylamino) -3-methyl-1-oxopentan-2-ylcarbamate, (1 in scheme), (1 mmol) in dichloromethane (CH₂Cl₂) (10 ml) at 273 K was added trifluoroacetic acid (TFA) (4 ml). After consumption of the starting material (2h), the solvent was then removed under reduced pressure to give a residue, which was extracted with CH₂Cl₂ (3 × 15 ml). The organic phase was dried over anhydrous MgSO₄ and concentrated under vacuum to obtain a slurry residue, which was purified by silica gel column chromatography (petroleum ether/isopropyl alcohol = 35:1) to give the title compound as a colorless amorphous solid. Single crystals of the title compound, suitable for X-ray diffraction analysis, were obtained by slow evaporation of a CH₂Cl₂ solution.

Refinement

All H atoms were placed in geometrically idealized positions and treated as riding on their parent atoms, with C—H = 0.93 (aromatic), 0.96 (CH₃), 0.97 (CH₂) and 0.98 (CH), N—H = 0.86 Å with U_iso(H) = k × U_eq(C or N), where k = 1.5 for methyl and amine H-atoms and 1.2 for all other H-atoms.

Special details

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.
