(Received 11 March 2004; accepted 22 March 2004; online 31 March 2004)

The relative configuration of the title compound, C18H27NO4, was determined as being R,S,S,S. There are three crystallographically independent mol­ecules in the asymmetric unit, which show only slight conformational differences. Molecules in the crystal structure are connected by hydrogen bonds in ribbons along the a axis.

Comment

Appropriate derivatives of the new natural products belactosins A, (1[link]), C, (2a[link]), and its homo-analogue, (2b[link]) (see scheme), are highly active proteasome inhibitors (Asai et al., 2000[Asai, A., Hasegawa, A., Ochiai, K., Yamashita, Y. & Mizukami, T. (2000). J. Antibiot. 53, 81-83.], 2004[Asai, A.,Tsujita, T., Sharma, S. V., Yamashita, Y., Akinaga, S., Funakoshi, M., Kobayashi, H., Mizukami, T. & Asahi-machi, M.-S. (2004). Biochem. Pharmacol. 67, 227-234.], Mizukami et al., 1997[Mizukami, T., Asai, A., Yamashita, Y., Katahira, R., Hasegawa, A., Ochiai, K. & Akinaga, S. (1997). Eur. Pat. Appl. EP 7 683 17 A1; Kyowa Hakko Kogyo Co., Ltd, Japan.]), which show an impressive potential against some types of cancer and inflammatory diseases (Gillessen et al., 2002[Gillessen, S., Groettrup, M. & Cerny, T. (2002). Onkologie, 25, 534-539.]; Almond & Cohen, 2002[Almond, J. B. & Cohen, G. M. (2002). Leukemia, 16, 433-443.]; Elliot et al., 2003[Elliot, P. J., Zollner, T. M. & Boehncke, W.-H. (2003). J. Mol. Med. 81, 235-245.]). In continuation of our search for synthetic approaches to enantioselective total syntheses of belactosins (Brandl et al., 2000[Brandl, M., Kozhushkov, S. I., Loscha, K., Kokoreva, O. V., Yufit, D. S., Howard, J. A. K. & de Meijere, A. (2000). Synlett, 12, 1741-1744.]) a precursor of the β-lactone moiety (3[link]) was prepared (Larionov & de Meijere, 2004[Larionov, O. V. & de Meijere, A. (2004). Org. Lett. Submitted.]). The absolute configuration of the β-lactone cycle of the natural products (1)–(3) is (2R,3S,4S), so it was crucial to establish the relative configuration of these centres in (3[link]). Unfortunately, compound (3[link]) is liquid under ambient conditions and a crystalline derivative of (3[link]) had to be prepared. After some experiments, the solid amide (4[link]) was obtained by the reaction of (3[link]) with (S)-α-phenyl­ethyl­amine (see scheme). The X-ray crystal structure of amide (4[link]) is reported in this paper.[link]

[Scheme 1]

There are three independent mol­ecules of (4[link]) in the asymmetric unit (Fig. 1[link]). They all have the same configuration at their chiral centres, but differ by the orientation of the ethyl groups (C11) and phenyl rings (Fig. 2[link]). The absolute configuration of the compound was assigned on the basis of the known S configuration of the α-phenyl­ethyl­amine, used in the synthesis of (4[link]). The terminal ethoxy group of one of the mol­ecules is disordered over two positions; the atoms of the ethoxy groups in the other two mol­ecules also show high anisotropic displacement parameters and are probably also slightly disordered. The molecular geometry of (4[link]) does not reveal any remarkable features. In the crystal structure, the mol­ecules are linked together by pairs of strong O1—H⋯O2 and N1—H⋯O4 hydrogen bonds (Fig. 3[link] and Table 1[link]), forming ribbons which are parallel to the a direction (Fig. 4[link]). Each ribbon is composed of one of the crystallographically independent mol­ecules and its symmetry-equivalents.

All H atoms were located in difference Fourier maps and included in the refinement in the riding mode, with isotropic displace­ment parameters of 1.5 (H atoms of methyl groups) and 1.2 (all other H atoms) times Ueq of the parent atom. H atoms of oxy groups were refined freely with Uiso equal 1.5Ueq of corresponding O atom. In the absence of significant anomalous scattering effects, Friedel pairs have been merged. The absolute configuration can not be determined from the diffraction data, but is known from the synthesis and has been assumed in the refinement.

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.
