To a solution of thiomorpholine (1 equiv.) and dry K2CO3 in benzene, ethyl 1-(2-bromopropanoyl)-4-hydroxy-2,6-diphenyl-1,2,5,6-tetrahydropyridin-3- carboxylate (1 equiv.; Aridoss, Gayathri et al., 2009) in benzene was added slowly over a period of 15 minutes and refluxed over night. After the completion of reaction, the contents were poured into water and extracted twice with ethyl acetate. The combined organic extracts were then washed well with brine and dried over anhydrous sodium sulfate. This upon evaporation, column purification and subsequent recrystallization in distilled ethanol afforded fine white crystals appropriate for X-ray diffraction study.
All H atoms were refined using a riding model, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic, C—H = 0.98 Å and Uiso(H) = 1.2Ueq(C) for CH, C—H = 0.97 Å and Uiso(H) = 1.2Ueq(C) for CH2, C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for CH3, and O—H = 0.82 Å and Uiso(H) = 1.5Ueq(O) for the OH group.

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. |

Our current research work is committed to find 2,6-diarylpiperidin-4-one based lead drug for the antimicrobial therapy and exploring the stereochemistry of its N-acyl derivatives (Aridoss, Balasubramanian, Parthiban, Ramachandran & Kabilan, 2007; Aridoss, Balasubramanian, Parthiban & Kabilan, 2007; Aridoss, Parthiban et al., 2009). Recently we have disclosed the crystal structure of ethyl 1-(2-bromopropanoyl)-4-hydroxy-2,6-diphenyl-1,2,5,6- tetrahydropyridin-3-carboxylate (Aridoss, Gayathri et al., 2009), which crystallizes with two independent molecules per asymmetric unit. Here, the tetrahydropyridine ring adopts a half-chair conformation in one molecule and distorted envelope conformation in other molecule. Thus to understand the change in conformation of the above said compound upon nucleophilic substitution of thiomorpholine in place of bromine, crystal structure of the title compound is determined by X-ray diffraction study and discussed in this paper.
The sum of the angles at N1 [358.6 (3)°] and N2 [336.1 (3)°] are in accordance with sp2 and sp3 hybridization, respectively. The dihedral angle between the two phenyl rings attached to the pyridine moiety is 21.8 (1)°. The thiomorpholine ring adopts chair conformation with atoms C9 and C11 deviating by 0.758 (2) and -0.673 (2) Å, respectively, from the least squares plane defined by atoms N2/C8/S1/C10. The tetrahydropyridine ring adops distorted envelope conformation. The puckering parameters (Cremer & Pople, 1975) and the smallest displacement asymmetry parameters (Nardelli, 1983) for thiomorpholine and tetrahydropyridine rings are q2 = 0.065 (1), 0.394 (1) Å, q3 = 0.639 (2), 0.294 (1) Å; QT = 0.642 (2), 0.491 (1) Å and θ = 5.7 (1), 53.3 (2)°, respectively.
The molecular structure and the crystal packing are stabilized by O—H···O intramolecular and C—H···O intermolecular interactions, respectively, with atom O3 acting as bifurcated acceptor. In intramolecular interaction, atom O2 acts as a donor to O3 generating an S(6) motif and in intermolecular interaction, atom C24 acts as a donor to atom O3 at (2 - x, -y, -z), generating a dimer of the type R22(18).
