1′-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.

In the title compound, C(27)H(24)N(2)O(3), the five-membered pyrroldine ring adopts an envelope conformation (with the N atom in the flap position) and the six-membered pyran-one ring of the coumarine ring system adopts a slightly distorted boat conformation. The oxindole unit makes dihedral angles of 89.7 (1) and 25.6 (1)°, respectively, with the pyrrolidine ring and the coumarin ring system. ...

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...

The title compound, C(20)H(17)N(3)O(2)S(2), crystallizes with two mol-ecules in the asymmetric unit. The pyrrolo-dine rings have envelope conformations in both mol-ecules, the N atoms deviating by 0.574 (3) and 0.612 (2) Å from the mean planes through the other ring atoms. The 1'-methyl and 4'-phenyl groups on the pyrrolidine rings are substituted in equatorial positions. In the crystal, mol-ec...
