Derivatives of tetrahydroquinolines display a wide range of physiological activities, they been found to be pesticides, antioxidants, photosensitizers, and dyes (Katritsky et al., 1996).
of 1,2,3,4-tetrahydroquinoline derivatives play important role in synthesize efficient with predominant (S,S)-(R,R)-diastereoisomers (Chulakov et al., 2012), optically active camphor moieties (Kadutskii et al., 2012), and biologically active compounds, synthetic intermediates (Keith et al., 2001).In due course of our study, we have synthised a series of 1,2,3,4-tetrahydroquinoline with derivatives of suloponyl chlorides they exhibit a few pharmacological activities (our unpublished data). As a part of our study we have undertaken
determination of the title compound and the results are compared with of 1-tosyl-1,2,3,4-tetrahydroquinoline(II) (Jeyaseelan et al., 2014) .The molecular structure of the title compound(I) is shown in Fig. 1. In both the compounds (I) and (II), the C1/C6–C9/N1 rings are in a half-chair conformation, with the methylene C9 atom as the flap, but the bond-angle sum at the N atom in the compound (I) and (II) are 347.9° and 350.2°, respectively.
In the crystal, inversion dimers linked by pairs of C10—H10C···O2 hydrogen bonds generate R22(8) ring motifs.
To a stirred solution of 1,2,3,4-tetrahydroquinoline (10 mmol) in 30 ml dry methylene dichloride, triethylamine (15 mmol) was added at 0 - 5°C. To this reaction mixture methanesulfonyl chloride (12 mmol) in 10 ml dry dichloromethane was added drop wise. After 2h of stirring at 15 - 20°C, the reaction mixture was washed with 5% Na2CO3 and brine. The organic phase was dried over Na2SO4 and then it was concentrated on vacuum to yield titled compound as colourless solid. The crude product was recrystallized from a slovent mixture of ethyl acetate and hexane(1:2) to yield colourless prisms of (I).
Crystal data, data collection and structure
details are summarized in Table 1. The H atoms were positioned with idealized geometry using a riding model with C—H = 0.93-0.99 Å. All H-atoms were refined with isotropic displacement parameters (set to 1.2-1.5 times of the U eq of the parent atom).Derivatives of tetrahydroquinolines display a wide range of physiological activities, they been found to be pesticides, antioxidants, photosensitizers, and dyes (Katritsky et al., 1996).

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. |
