Methyl 3′-(25-di­methyl­benz­yl)-1′-methyl-2-oxo-4′-phenyl­spiro­indoline-32′-pyrrolidine-3′-carboxyl­ate chloro­form monosolvate

摘要

In the title solvate, C29H30N2O3·CHCl3, the dihedral angle between the indole ring system (r.m.s. deviation = 0.050 Å) and the 4-methyl­pyrrolidine ring is 88.88 (8)°. The latter ring adopts an envelope conformation with the N atom as the flap. Its mean plane makes dihedral angles of 86.94 (11) and 42.08 (9)° with the phenyl and di­methyl­benzene rings, respectively. The mol­ecular conformation is stabilized by intra­molecular C—H⋯O hydrogen bonds, which generate S(6) and S(9) ring motifs. The chloro­form solvent mol­ecule is linked to the organic mol­ecule by a C—H⋯O hydrogen bond involving the carbonyl O atom of the carboxyl­ate group. In the crystal, mol­ecules are linked via bifurcated N—H⋯(N,O) and C—H⋯O hydrogen bonds, forming chains propagating along [001].
