Ethyl 7'-(6-benz-yloxy-2,2-dimethyl-tetra-hydro-furo[3,2-d][1,3]dioxol-5-yl)-2-oxo-5',6',7',7a'-tetra-hydro-1'H,2H-spiro-[acenaphthyl-ene-1,5'-pyrrolo-[1,2-c][1,3]thia-zole]-6'-carboxyl-ate.

ABSTRACT: In the title compound, C(34)H(35)NO(7)S, the acenaphthyl-ene unit is essentially planar (r.m.s. deviation = 0.0335 Å). The pyrrolo-thia-zole ring system is folded about the bridging N-C bond; the thia-zolidine and pyrrolidine rings adopt S- and C-envelope conformations, respectively, with a 'butterfly' angle between the mean planes of 51.38 (10)°. The dioxolane and tetra-hydro-furan rings adopt O- and a C-envelope conformations, respectively, with a 'butterfly' angle between the mean planes of 57.12 (10)°. Two C atoms are each disordered over two positions with site-occupancy factors of 0.450 (7) and 0.550 (7). The crystal packing is stabilized by C-H⋯O inter-actions, generating an R(2) (2)(14) graph-set ring motif.

Project description:The asymmetric unit of the title compound, C(28)H(21)NO(3)S, contains two mol-ecules with similar geometries. The thia-zolidine rings adopt half-chair conformations while the pyrrolidine and the diketo-substituted five-membered carbocyclic rings are in envelope conformations with the spiro C atoms at the flaps. In one mol-ecule, the phenyl ring forms dihedral angles of 57.76 (12) and 71.79 (12)° with the fused benzene rings and the fused benzene rings form a dihedral angle of 57.75 (13)°. The corresponding dihedral angles in the other mol-ecule are 60.04 (12), 72.93 (12) and 54.51 (13)°. The mol-ecular structure is stabilized by intra-molecular C-H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal, mol-ecules are linked via C-H⋯O and C-H⋯N hydrogen bonds into layers lying parallel to the ab plane.

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.

The crystal packing also features pairs of C-H⋯π inter-actions, which link the dimers into a supra-molecular chain along the b axis.
