1′-Methyl-4′-(1-naphthyl)-1′′,2′′,3′′,4′′-tetrahydroindane-2-spiro-2′-pyrrolidine-3′-spiro-2′′-naphthalene-1,3,1′′-trione
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⋯π inter-action ar...

Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
متن کامل4′-Ferrocenyl-1′-methylacenapthylene-1-spiro-2′-pyrrolidine-3′-spiro-2′′-indane-2,1′′,3′′(1H)-trione
In the title compound, [Fe(C(5)H(5))(C(29)H(20)NO(3))], the acenaphthyl-ene ring system makes a dihedral angle of 83.77 (3)° with the indane-1,3-dione ring system. The central pyrrolidine ring exhibits a twist conformation. In the crystal, mol-ecules are linked by a weak inter-molecular C-H⋯O inter-action into a chain along the b axis. Two weak intra-molecular C-H⋯O inter-actions are also present.

In the title compound, C(21)H(15)N(5)O(2), the pyrrolidine ring adopts a twist conformation. Both the oxindole rings are planar [maximum deviations of 0.076 (1) and 0.029 (1) Å in the two rings] and are oriented at a dihedral angle of 72.7 (1)°. The crystal structure is stabilized by C-H⋯O, N-H⋯O, N-H⋯N and C-H⋯π inter-actions.

In the title mol-ecule, C(29)H(22)ClN(3)S, the quinoline ring system, thio-phene ring and phenyl ring substituents are inclined at angles of 71.70 (7), 59.26 (9) and 81.61 (9)°, respectively, to the 4,5-dihydro-pyrazole ring. In the 4-phenyl-quinoline ring system, the phenyl ring makes a dihedral angle of 62.49 (7)° with mean plane of quinoline ring system. In the crystal structure, mol-ecules ...
