1′-Methyl-4′-(1-naphthyl)-3′′-(1-naphthylmethylene)acenaphthene-1-spiro-2′-pyrrolidine-3′-spiro-1′′-cyclohexane-2,2′′-dione
In the title compound, C(42)H(33)NO(2), the six-membered cyclo-hexa-none ring adopts a slightly distorted chair conformation and the five-membered pyrrolidine ring is in an envelope conformation. The mol-ecular structure features four intra-molecular C-H⋯O inter-actions and an intra-molecular C-H⋯π inter-action. Furthermore, the crystal packing is stabilized by an inter-molecular C-H⋯O and thre...

In the title compound, C(26)H(22)N(2)O(3), the acenaphthen-1-one ring system is nearly planar and the pyrrolidine ring adopts a distorted envelope conformation. An inter-molecular C-H⋯O hydrogen bond stabilizes the crystal structure.
متن کامل1′-Methyl-4′-[4-(trifluoromethyl)phenyl]dispiro[acenaphthylene-1,2′-pyrrolidine-3′,2′′-indane]-2,1′′(1H)-dione
In the title compound, C(31)H(22)F(3)NO(2), the pyrrolidine and cyclo-pentane rings within the dihydro-indene ring system are in envelope conformations, with the N atom and the spiro-C atom at the flap, respectively. An intra-molecular C-H⋯O hydrogen bond forms an S(8) ring motif. The mean plane through the pyrrolidine ring [r.m.s. deviation = 0.179 (2) Å] makes dihedral angles of 86.30 (13), 8...

In the title mol-ecule, C(27)H(24)N(2)O(2), the pyrrolidin-2-one ring is almost planar (r.m.s. deviation = 0.003 Å), the pyrrolidine ring has an envelope conformation (the N atom is the flap atom) and the cyclo-penta-none ring is twisted about the C(q)-C(m) bond (q = quaternary and m = methylene). The ketone O atoms are directed to opposite sides of the mol-ecule. Supra-molecular chains along t...
متن کامل1′-Methyl-4′-(4-methylphenyl)dispiro[1-benzopyran-3(4H),3′-pyrrolidine-2′,3′′-indoline]-2,2′′-dione
In the title compound, C(27)H(24)N(2)O(3), the pyrroldine ring adopts a twist conformation, while the six-membered pyran-one ring of the coumarin ring system is in a sofa conformation. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion R(2) (2)(8) dimers. These dimers are further connected via C-H⋯O hydrogen bonds.
