The title compound, C8H12N+·C23H36NO3·H2O, has one mol­ecule of N-tetra­deca­noyl-L-phenyl­alanine and one mol­ecule of (R)-1-phenyl­ethyl­amine as a diastereoisomeric salt, and a water mol­ecule in the asymmetric unit. In the crystal structure, the packing of the mol­ecules is stabilized by N—H...O and O—H...O hydrogen bonds involving the amide, ammonium and carboxyl­ate groups, and the solvent water mol­ecule.

Comment top

N-Acyl amino acids are generally formed by condensation of amino acids with fatty acids and produce water-soluble anionic surfactants when their acid moieties are neutralized with a range of bases. These compounds are widely used as additives, dispersants and detergents in a variety of industrial and commercial applications due to their biodegradability and low toxicity (Takehara, 1984). There are also growing concerns over the molecular associations of chiral surfactants (Shinitzky & Haimovitz, 1993; Parazak et al., 1994; Ohta et al., 2003) and their applications to chiral analytical techniques such as electrophoresis (Taurus et al., 2003). When N-acyl amino acids are neutralized with optically active bases, diastereoisomeric surfactant salts are formed. Structural studies on these diastereomeric salts may provide the basis for understanding the mechanism of chiral discrimination of N-acyl amino acid surfactants. In this work, we have prepared a diastereomeric salt, (I), from N-tetradecanoyl-L-phenylalanine and (R)-1-phenylethylamine as a model of chiral discrimination of N-acyl amino acids and determined its structure.

The conformation of the tetradecanoyl chain is as most often found for larger alkanes, i.e. staggered with the largest substituents at any C—C bond antiperiplanar with respect to each other (Fig. 1). The C—C bond lengths within the chain range from 1.518 (6) to 1.533 (5) Å and the anglesfrom 112.8 (3) to 114.1 (3)°. These values are similar to those found in a related fatty acid (Amai et al., 1998).

The molecular packing is such that the hydrocarbon chains lie side by side, with neighboring hydrophillic heads pointing in opposite directions. The hydrophilic heads are connected by a network of hydrogen bonds involving the carboxylate group of N-tetradecanoyl-L-phenylalanine, the ammonium group of (R)-1-phenylethylamine and the water molecule (Table 1 and Fig. 2). The amide linkages of N-tetradecanoyl-L-phenylalanine molecules form a N—H···O hydrogen-bondied chain running along the b axis.

Experimental top

N-tetradecanoyl-l-phenylalanine was prepared by the reaction of l-phenylalanine with tetradecanoyl chloride as described previously (Miyagishi & Nishida, 1978) and was recrystallized from an acetone/methanol solution three times. The purity was checked by HPLC and DSC and by observing no minimum on the surface tension vs concentration curves at 298.15 K. The title compound was obtained by neutralization of N-tetradecanoyl-l-phenylalanine with equimolar of (R)-1-phenylethylamine in methanol. After evaporation of the solvent, the residue was recrystallized from a methanol/water solution to obtain suitable crystals for X-ray diffraction (m.p. 374–376 K).

Refinement top

H atoms involved in hydrogen bonds were located in a difference map, and their positional parameters were refined. The Uiso(H) values were set at 1.2Ueq(N or O). Other H atoms were included in calculated positions using a riding-model approximation, with C—H distances in the range 0.93–0.97 Å and Uiso(H) = 1.2Ueq(C). Due to the absence of any significant anomalous scatterers in the crystal, Friedel pairs were merged before the final refinement. The absolute configuration has been assigned on the basis of the known configuration of the reagents.
