(Received 12 March 2012; accepted 16 March 2012; online 21 March 2012)

In the title molecule, C₂₈H₃₃FN₂O₅S, the mean plane about the tertiary amine group (sum of the angles subtended at the sp²-hybridized N atom = 359.7°) forms a dihedral angle of 16.66 (6)° with the phenyl ring adjacent to the carbamate group. The sulfonamide benzene ring and the hydroxy group lie to either side of the C₂NS plane, whereas the benzylphenyl (connected to the N atom) and carbamate substituents lie to the other side. Supramolecular layers propagating in the ac plane are found in the crystal, linked by hydroxy–sulfonamide O—H⋯O and carbamate–carbamate N—H⋯O hydrogen bonds along with C—H⋯O and C—H⋯π interactions.

Comment top

Tuberculosis, TB, once again is becoming a worldwide problem due mainly to the increase in numbers of people infected with the HIV virus (de Souza, 2006). In 2010, there were 1.1 million new cases of TB among people living with HIV. Of the 1.8 million HIV-related deaths in 2010, 350,000 were due to TB (www.who.int/hiv/topics/tb/hiv_tb_factsheet_june_2011). Beta-aminoalcohols are actively being considered as a promising class of compounds in the combat of co-infection by TB and HIV, due to its versatility and significant application in anti-TB and anti-HIV treatment (Yendapally et al., 2008; Ferreira et al., 2009; Cunico et al., 2008; Cunico et al., 2011; Gomes et al., 2011). We now wish to report the structure of the title compound, 3, prepared as shown in Fig. 1.

Compound 3, Fig. 2, the tertiary amine is sp² hybridized as evidenced by the sum of the angles subtended at the N1 atom of 359.7°. The sulfonamide-benzene and benzyl-phenyl rings connected to the N1 atom are almost orthogonal to each other, with the dihedral angle between them being 73.86 (11)°, and lie to either side of the C₂NS plane. The hydroxy group is orientated to the same side of the molecule as the sulfonamide-benzene ring, and the carbamate group to the same side as the benzyl-phenyl ring. The dihedral angle between the carbamate group and adjacent phenyl ring is 66.35 (8)°, with the latter approximately parallel with the C₂NS plane, forming a dihedral angle of 16.66 (6)°.

In the crystal packing, the hydroxy group forms a hydrogen bond with a sulfonamide-O atom, and the carbamate-N—H and O atoms self-associate, Table 1. These interactions are reinforced by C—H···O and C—H···π interactions, Table 1, to form a supramolecular layer in the ac plane, Fig. 3. Layers stack along the b axis with no specific intermolecular interactions between them, Fig. 4.

Experimental top

A solution of (2S,3S)-boc-phenylalanine epoxide, 1, (1.6 mmol) and benzylamine (1.5 mmol) in i-PrOH (10 ml) was refluxed for 16 h. The reaction mixture was rotary evaporated and the crude product, 2, was crystallized from aqueous MeOH. To a solution of 2 in CH₂Cl₂ (10 ml) was successively added trifluoroacetic acid (2.2 mmol) and DMF (0.2 mmol). The mixture was stirred for 30 min under nitrogen, 4-fluorobenzenesulfonyl chloride (2.0 mmol) was added portion wise, After stirring for 8 h, the reaction mixture was washed with 5% HCl aqueous solution, water, brine, dried over MgSO₄ and rotary evaporated to give the title compound, 3, which was recrystallized from EtOH to provide colourless blocks, M.pt: 418–420 K.

Special details top

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