1-Methyl-3,5-bis[(E)-4-methoxyphenylmethylidene]tetrahydro-4(1H)-pyridinone (1 mmol), acenaphthenequinone (0.182 g, 1 mmol) and 1,3-thiazolane-4-carboxylic acid (0.133 g, 1 mmol) were dissolved in methanol (10 ml) and refluxed for 30 min. After completion of the reaction, as evident from TLC, the mixture was poured into water (50 ml). The precipitated solid was filtered and washed with water (100 ml) to obtain the pure product as a solid. The product was recrystallized from ethyl acetate to obtain suitable crystals for the X-ray analysis. Melting point: 479 K; Yield: 89%.
H atoms were placed at calculated positions and allowed to ride on their carrier atoms with C—H = 0.93–0.98 Å. Uiso = 1.2Ueq(C) for CH2 and CH groups, and Uiso = 1.5Ueq(C) for CH3 groups.
Spiro-compounds represent an important class of naturally occurring substances, which in many cases exhibit important biological properties (Kobayashi et al., 1991; James et al., 1991). 1,3-Dipolar
reactions are widely used for the construction of spiro-compounds (Caramella & Grunanger, 1984).In the title compound (Fig. 1), the six-membered piperidine ring adopts a half-chair conformation with atoms N1 and C5 deviating by -0.532 (2) and -0.588 (2) Å, respectively, from the least-squares plane defined by atoms C2/C3/C4/C6. In the pyrrole thiazole fused ring system, the pyrrole ring has an
and the thiazole ring is in a twisted with C8 atoms being the flap atom in both of these envelopes. The twisted of the thiazole ring may be due to the intramolecular C10—H10B···O2 interaction (Table 1). Similarly the orientation of the 4-methoxyphenyl substituent with respect to the attached piperidine ring may be influenced by the intermolecular C34—H34···O1 interaction (Table 1). The dihedral angle between the methoxyphenyl rings are 86.4 (1)°, and these rings form dihedral angles of 59.1 (1) and 39.8 (1)° with the acenaphthene group.The C72—H72···O2 hydrogen bond connect two centrosymmetrically related molecules and generate the graph set motif R22(16) (Bernstein et al., 1995), Fig. 2. These dimers are connected into a zigzag chain by C34—H34···O1 hydrogen bonds (Fig. 2). In addition, there are two weak C—H···π interactions, Table 1.

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. |

Spiro-compounds represent an important class of naturally occurring substances, which in many cases exhibit important biological properties (Kobayashi et al., 1991; James et al., 1991). 1,3-Dipolar cycloaddition reactions are widely used for the construction of spiro-compounds (Caramella & Grunanger, 1984).
In the title compound (Fig. 1), the six-membered piperidine ring adopts a half-chair conformation with atoms N1 and C5 deviating by -0.532 (2) and -0.588 (2) Å, respectively, from the least-squares plane defined by atoms C2/C3/C4/C6. In the pyrrole thiazole fused ring system, the pyrrole ring has an envelope conformation, and the thiazole ring is in a twisted envelope conformation with C8 atoms being the flap atom in both of these envelopes. The twisted envelope conformation of the thiazole ring may be due to the intramolecular C10—H10B···O2 interaction (Table 1). Similarly the orientation of the 4-methoxyphenyl substituent with respect to the attached piperidine ring may be influenced by the intermolecular C34—H34···O1 interaction (Table 1). The dihedral angle between the methoxyphenyl rings are 86.4 (1)°, and these rings form dihedral angles of 59.1 (1) and 39.8 (1)° with the acenaphthene group.
The C72—H72···O2 hydrogen bond connect two centrosymmetrically related molecules and generate the graph set motif R22(16) (Bernstein et al., 1995), Fig. 2. These dimers are connected into a zigzag chain by C34—H34···O1 hydrogen bonds (Fig. 2). In addition, there are two weak C—H···π interactions, Table 1.
