(Received 10 September 2009; accepted 17 September 2009; online 3 October 2009)

The bond distances and bond angles of the title compound, C23H25NO6, are consistent with values typically found for fluoren-9-ylmethoxy­carbonyl-protected amino acids. The conformations of the backbone and the side chain are slightly different from those of L-aspartic acid. The crystal structure exhibits two inter­molecular hydrogen bonds, forming a two-dimensional sheet structure parallel to the ab plane.

Comment top

L-Aspartic acid is one of the 20 building blocks of proteins, and, in mammals, can be produced from oxaloacetate by transamination. As for the related compounds of an aspartic acid, the crystal structures of L-aspartic acid (Derissen et al.,1968; Bendeif & Jelsch, 2007), L-aspartic acid monohydrate (Umadevi et al., 2003), DL-aspartic acid (Sequeira et al., 1989; Flaig et al., 1998; Rao, 1973; Wang et al., 2007), and DL-aspartic acid hydrochloride (Dawson, 1977) have been reported so far.

Fluoren-9-ylmethoxycarbonyl (Fmoc) group is widely used for solid-phase peptide synthesis protocols as an N-α-protecting group. To our best knowledge, however,there have been only four literatures reporting crystal structures of Fmoc-protected amino acids (Valle et al., 1984; Yamada, Hashizume & Shimizu, 2008; Yamada, Hashizume, Shimizu & Deguchi, 2008; Yamada, Hashizume, Shimizu, Ohiki & Yokoyama, 2008). In this communication, the crystal structure of N-Fmoc-protected aspartic acid 4-tert-butyl ester (I) is reported.

The molecular structure of (I) is shown in Fig. 1 together with the atom labeling. The bond lengths and angles of the present molecule are in reasonable agreement with typical values found in L-aspartic acids and the related compounds. The conformations of the backbone and the side-chain, however, are slightly different from those of L-aspartic acid. The torsion angles, N1–C1–C2–C3 and N1–C1–C4–O4, are found to be 62.5 (4) and 17.0 (5)°, respectively. For L-aspartic acid, the corresponding angles are -60.3 and -39.2°, respectively. In the Fmoc-protected amino acids, the fluoren moiety takes various conformations as shown in the available literatures. In this case, the conformation of the Fmoc moiety is similar to those of Fmoc-protected isoleucine and serine.

Fig. 2 shows the crystal structure of (I). The molecules are linked via intermolecular hydrogen bonds between carboxyl and Fmoc moieties, O3–H3···O5 to form the column around the 21 screw axis parallel to the b axis. The columns, related by translation symmeties along the a axis each other, are joined together through weak hydrogen bonds between the amino and carboxyl groups, N1—H1···O3, two-dimensional sheet structures are formed paralell to the ab plane consequentry. The geometries of the hydrogen bonds are listed in Table 2.

Experimental top

A powdered sample of the title compound was purchased from Wako Pure Chemical Industries, Ltd. (Osaka, Japan). Single crystals suitable for X-ray structure analysis could be obtained by recrystallization from ethyl acetate-dichloromethane (80:20) solution, which afforded white needle-like crystals.

Refinement top

All H atoms were located on the difference maps, and were treated as riding atoms with C/N/O–H distances of 1.00, 0.99, 0.98, 0.95, 0.88 and 0.84 Å, for methyne, methylene, methyl, phenyl, amino and hydroxyl groups, respectively, on the refinements. The Uiso's of the H atoms were fixed to be 1.2Ueq(C/N) for methyne, methylene, phenyl and amino, or 1.5Ueq(C/O) for methyl and hydroxyl of the parent atoms.

All Friedel pairs were merged, and all f"s of containing atoms were set to zero.

Special details top

Experimental. All Friedel pairs were merged, and all f"s of containing atoms were set to zero.

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 al 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 > 2σ(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.
