1′,3′,3′-Trimethyl-2,3-diphenyl-2,3-dihydroisoxazole-5(4H)-spiro-2′-indoline
Two diastereoisomers of the title compound, C(25)H(26)N(2)O, have been prepared by cyclo-addition between 1,3,3-trimethyl-2-methyl-eneindoline and C-phenyl-N-phenyl-nitrone. The stereochemistry of the major diastereoisomer, viz. S,R/R,S, is confirmed by the X-ray analysis. The oxazole and the pyrole rings have envelope conformations. The packing is stabilized by weak C-H⋯π inter-actions involvi...

In the title compound, C(33)H(28)N(2)O(4), the central pyrrolidine ring adopts a half-chair conformation. Both the indolinone and indanone groups are twisted, with their five-membered rings adopting a half-chair and an envelope conformation, respectively. The two benzene rings and the mean plane of the indolinone and indanone groups make dihedral angles of 71.98 (10), 84.32 (10), 86.26 (9) and ...

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 compound, C(23)H(23)Cl(2)N(3)O(2), the pyrroline ring adopts an envelope conformation and the piperidinone ring assumes a slightly twisted chair form. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate an R(2) (8) graph-set motif and a short Cl⋯Cl contact of 3.478 (1) Å occurs.
