1'-Methyl-4'-(1-naphth-yl)-1'',2'',3'',4''-tetra-hydro-indane-2-spiro-2'-pyrrolidine-3'-spiro-2''-naphthalene-1,3,1''-trione.

ABSTRACT: In the title compound, C(32)H(25)NO(3), the pyrrolidine ring adopts an envelope conformation, whereas the cyclo-hexa-none ring in the tetra-hydro-naphthalene fused-ring system adopts a half-chair conformation. The indanedione unit is oriented at an angle of 58.9?(1)° with respect to the naphthyl ring system. Three intra-molecular C-H?O close contacts and an intra-molecular C-H?? inter-action are observed. In the crystal, mol-ecules associate via C-H?O hydrogen bonds, forming a helical chain with a C(10) motif along the b axis.

4'-(4-Fluoro-phen-yl)-1'-methyl-dispiro-[indane-2,2'-pyrrolidine-3',2''-indane]-1,3,1''-trione methanol hemisolvate.

Project description:The asymmetric unit of the title compound, C29H24FNO5·0.5CH3OH, contains two independent mol-ecules and a one methanol solvent mol-ecule. The methanol mol-ecule is O-H?O hydrogen bonded to one of the independent mol-ecules. The pyrrolidine rings in both mol-ecules adopt half-chair conformations, while the cyclo-pentane rings within the indane groups are in flattened envelope conformations, with the spiro C atoms forming the flaps. The benzene rings of the indane ring systems form a dihedral angle of 35.06?(7)° in one independent mol-ecule and 31.16?(8)° in the other. The fluoro-substituted benzene ring forms dihedral angles of 65.35?(6) and 85.87?(7)° with the indane group benzene rings in one mol-ecule, and 72.78?(8) and 77.27?(8)° in the other. In each mol-ecule, a weak intra-molecular C-H?O hydrogen bond forms an S(6) ring motif. In the crystal, weak C-H?O, C-H?N and C-H?F hydrogen bonds link the mol-ecules into a three-dimensional network.

8,8-Diethyl-1,4,5,8-tetra-hydro-naphthalene-1,4,5-trione.

Project description:The title mol-ecule, C(14)H(14)O(3), contains two fused six-membered carbon rings with keto groups at positions 1, 4 and 5 and a gem-diethyl group at position 8. The mol-ecule is close to planar (maximum deviation = 0.044?Å), with one ethyl group at each side of the mol-ecular plane, with exception of the keto group at position 1 which is slightly deviated from the plane and disordered over two positions one on each side of it (occupancies 0.80/0.20). The packing of the mol-ecule shows weak bonded chains along a through C-H?O contacts and two intramolecular C-H?O interactions are also present.
