1',3',3'-Trimethyl-2,3-diphenyl-2,3-di-hydro-isoxazole-5(4H)-spiro-2'-indoline.

ABSTRACT: 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?? inter-actions involving the phenyl ring attached to the N atom of the oxazole and the phenyl ring of the indole fragment.

1,2-Di-hydro-spiro-[carbazole-3(4H),2'-[1,3]dioxolane].

Project description:In the title compound, C(14)H(15)NO(2), the hydrogenated six-membered ring of the carbazole unit adopts a half-chair conformation and the dioxolane ring points to one side of the carbazole plane. Neighbouring mol-ecules form edge-to-face inter-actions in which the NH group is directed towards an adjacent carbazole unit, with a shortest H?C contact of 2.72?Å. These inter-actions arrange the mol-ecules into one-dimensional herringbone-type motifs, which pack so that the methyl-ene groups of the dioxolane ring lie over the face of a neighbouring carbazole unit with a shortest H?C contact of 2.85?Å.

The crystal structure is stabilized by N-H?N hydrogen-bonding inter-actions, leading to a zigzag chain along the b axis.

The phenyl substituents are almost perpendicular to each other [dihedral angle 87.06 (9)°]. In the crystal, mol-ecules are linked into chains parallel to the c axis through C-H⋯O inter-actions.

Project description:The phenyl and tert-butyl groups of the title compound, C27H25NO3, exhibit a trans configuration in agreement with the stereochemistry of the Z phenyl-N-tert-butyl-nitrone starting material.

The dihedral angle between the di-hydro-isoxazole ring and the directly attached phenyl group is 86.86 (8)°. There are two nonclassical inter-molecular C-H⋯O hydrogen-bonding inter-actions that operate together with an inter-molecular C-H⋯π inter-action to form a supramolecular architecture in the crystal system.
