7'-Phenyl-1',3',5',6',7',7a'-hexa-hydro-dipiro[acenaphthyl-ene-1,5'-pyrrolo-[1,2-c]thia-zole-6',2''-indane]-2,1''(1H)-dione.

ABSTRACT: In the title compound, C(31)H(23)NO(2)S, the pyrrolidine ring adopts an envelope conformation (with the spiro C atom as the flap), while the thia-zolidine ring and the two cyclo-pentane rings adopt twisted conformations. The mean plane through the hexa-hydro-pyrrolo-[1,2-c]thia-zole ring [r.m.s deviation = 0.400?(1)?Å] forms dihedral angles of 76.83?(4), 80.70?(5) and 79.00?(4)° with the benzene ring and the mean planes of the dihydro-acenaphthyl-ene and the dihydro-indene rings, respectively. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds into sheets lying parallel to the bc plane. One of the ketone O atoms accepts three such bonds. Weak C-H?? inter-actions are also observed.

Project description:The title compound, C35H28N4O6S, crystallizes with two mol-ecules in the asymmetric unit. In both mol-ecules, the piperidine ring adopts a shallow-chair conformation, the thia-zole ring adopts a twisted conformation about the Cm-N bond (m = methine) and the pyrrole ring adopts an envelope conformation with the C atom shared with the thia-zole ring as the flap. In the crystal, inversion dimers linked by pairs of C-H?O inter-actions generate R 2 (2)(34) loops for one of the asymmetric mol-ecules. Further C-H?O links also involving the other mol-ecule lead to a three-dimesional network. The contribution of the highly disordered solvent to the scattering was removed with SQUEEZE option of PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]. The solvent contribution is not included in the reported mol-ecular weight and density.

Project description:In the title compound, C39H36N2O4S, the piperidine ring adopts a twisted half-chair conformation. In the pyrrolo-thia-zole fused-ring system, the pyrrole ring adopts an envelope conformation (with the C atom bound to the thia-zole ring being the flap atom) and the thia-zole ring also exhibits an envelope conformation (with the N atom bound to the pyrrole ring as the flap).

Project description:In the title compound, C40H29N3O3S, the pyran ring adopts a sofa conformation, the thia-zolidine ring adopts a twisted conformation and the pyrrolidine ring adopts an envelope conformation with the N atom as the flap. The pyrazole ring is essentially planar [maximum deviation = 0.002?(2)?Å] and forms dihedral angles of 4.8?(1) and 39.0?(1)°, respectively, with the benzene rings attached to the N and C atoms. The acenapthylene ring system is approximately planar [maximum deviation = 0.058?(2)?Å] and forms dihedral angles of 85.9?(1) and 48.5?(1)°, respectively, with the pyrollothia-zole and chromene ring systems. The mol-ecular conformation is stabilized by three weak intra-molecular C-H?O hydrogen bonds, which generate one S(8) and two S(6) ring motifs. In the crystal, pairs of C-H?O hydrogen bonds link centrosymmetrically related mol-ecules into dimers, generating R 2 (2)(14) ring motifs. The crystal packing also features pairs of C-H?? inter-actions, which link the dimers into a supra-molecular chain along the b axis.

The two independent mol-ecules are disposed about a pseudo center of inversion and are connected by a pair of N-H?O hydrogen bonds. Adjacent dimers are linked by a pair of O-H?O hydrogen bonds, generating a chain running along the b axis.

4'-(4-Bromo-phen-yl)-1'-methyl-dispiro-[acenaphthyl-ene-1,2'-pyrrolidine-3',2''-indane]-2,1''(1H)-dione.

Project description:In the title compound, C(30)H(22)BrNO(2), the cyclo-pentane ring of the dihydro-acenaphthyl-ene group and the pyrrolidine ring are both in envelope conformations with the spiro C atom and N atom, respectively, as the flap atom.
