In the title compound, C25H22ClNO3S, both the pyrrolidinyl and thiazolyl rings adopt envelope conformations whereas the dihydropyran ring adopts a half-chair conformation. The chlorophenyl and naphthalenyl ring systems are oriented at a dihedral angle of 59.7 (1)°. The crystal packing is stabilized by an intramolecular C—H⋯N hydrogen bond and weak intermolecular C—H⋯π interactions.

A mixture of (Z)-methyl-2[(1-formylnaphthalen-2-yloxy)methyl]-3-(4-chlorophenyl) acrylate (20 mmol) and thiaproline (30 mmol) was refluxed in benzene for 20 h and the solvent was removed under reduced pressure. The crude product was subjected to
to get the pure product. Single crystals were grown by slow evapoartion of a chloroform-methanol (1:1) soution.H atoms were placed in idealized positions and allowed to ride on their parent atoms, with C—H = 0.93, 0.98, 0.97 and 0.96 Å for aromatic, methine, methylene and methyl H respectively, and Uiso(H) = 1.5Ueq(C) for methyl H and Uiso(H) = 1.2Ueq(C) for all other H atoms.
In continuation of our work on the
analysis of pyrrolizine derivatives, we have undertaken a single-crystal X-ray diffraction study for the title compound, and the results are presented here.The X-ray study confirmed the molecular structure and atomic connectivity for (I), as illustrated in Fig. 1. A l l the bond lengths are normal and comparable to the standard values. Fig. 2 shows a superposition of the pyrrolidine ring of (I) with the related reported structures of Nirmala et al. (2009) and Selvanayagam et al. (2010), using Qmol (Gans & Shalloway, 2001); the r.m.s. deviation is 0.350 and 0.864 Å, respectively. The sum of the angles (331.9°) around atom N1 is in accordance with sp3 hybridization.
The chlorine atom deviates 0.118 (1) Å from the best plane of chlorophenyl ring. The naphthalene ring system (C2–C11) and the chlorophenyl ring are oriented with a dihedral angle of 59.7 (1)°. In the thiapyrrolizine ring system, both the pyrrolidine and thiazole rings N1/C1/C13–C15 and N1/C15/C16/S1/C17 adopt envelope conformations; the puckering parameters (Cremer & Pople, 1975) are: q2 = 0.447 (2) Å and φ = -118.7 (2)° for N1/C1/C13–C15 ring, and q2 = 0.508 (2) Å and φ = -59.9 (2)° for N1/C15/C16/S1/C17 ring. In the N1/C1/C13–C15 ring, atom C13 deviates by -0.675 (2) Å from the least-squares plane through the remaining four atoms, whereas in the ring N1/C15/C16/S1/C17, atom S1 deviates by -0.855 (1) Å from the plane through the remaining four atoms. The dihydropyran ring of the chromene unit adopts a half-chair conformation, with the lowest asymmetry parameter ΔC2(C2–C11) of 0.039 (1)° (Nardelli, 1983).
In addition to van der Waals interactions, the molecular packing is stabilized by intramolecular C—H···N hydrogen bond and intermolecular weak C—H···π interactions (Fig. 3).

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. |

In continuation of our work on the crystal structure analysis of pyrrolizine derivatives, we have undertaken a single-crystal X-ray diffraction study for the title compound, and the results are presented here.
The X-ray study confirmed the molecular structure and atomic connectivity for (I), as illustrated in Fig. 1. A l l the bond lengths are normal and comparable to the standard values. Fig. 2 shows a superposition of the pyrrolidine ring of (I) with the related reported structures of Nirmala et al. (2009) and Selvanayagam et al. (2010), using Qmol (Gans & Shalloway, 2001); the r.m.s. deviation is 0.350 and 0.864 Å, respectively. The sum of the angles (331.9°) around atom N1 is in accordance with sp3 hybridization.
The chlorine atom deviates 0.118 (1) Å from the best plane of chlorophenyl ring. The naphthalene ring system (C2–C11) and the chlorophenyl ring are oriented with a dihedral angle of 59.7 (1)°. In the thiapyrrolizine ring system, both the pyrrolidine and thiazole rings N1/C1/C13–C15 and N1/C15/C16/S1/C17 adopt envelope conformations; the puckering parameters (Cremer & Pople, 1975) are: q2 = 0.447 (2) Å and φ = -118.7 (2)° for N1/C1/C13–C15 ring, and q2 = 0.508 (2) Å and φ = -59.9 (2)° for N1/C15/C16/S1/C17 ring. In the N1/C1/C13–C15 ring, atom C13 deviates by -0.675 (2) Å from the least-squares plane through the remaining four atoms, whereas in the ring N1/C15/C16/S1/C17, atom S1 deviates by -0.855 (1) Å from the plane through the remaining four atoms. The dihydropyran ring of the chromene unit adopts a half-chair conformation, with the lowest asymmetry parameter ΔC2(C2–C11) of 0.039 (1)° (Nardelli, 1983).
In addition to van der Waals interactions, the molecular packing is stabilized by intramolecular C—H···N hydrogen bond and intermolecular weak C—H···π interactions (Fig. 3).
