Methyl (2Z)-2-bromo­methyl-3-(2,4-dichloro­phen­yl)prop-2-enoate

In the title compound C₁₁H₉BrCl₂O₂, which represents the Z isomer, the methyl­acrylate moiety is essentially planar within 0.039 (2) Å and has an extended trans configuration. The benzene ring makes a dihedral angle of 28.3 (1)° with the mean plane of the methyl­acrylate moiety. The crystal packing is characterized by C—H...O hydrogen bonding and halogen–halogen inter­actions [Cl...Cl = 3.486 (3) Å], resulting in the formation of R₂²(11) ring motifs and connecting the mol­ecules into chains propagating along the b axis.

Methyl 3′-benzyl-4′-(2-chloro­phen­yl)-1′-methyl-2-oxo­spiro­[indoline-3,2′-pyrrolidine]-3′-carboxyl­ate

In the title compound, C₂₇H₂₅ClN₂O₃, the methyl­pyrrolidine ring adopts an envelope conformation with the N atom at the flap. The mean plane of the pyrrolidine ring makes dihedral angles of 82.1 (1), 84.4 (1) and 79.8 (1)°, respectively, with the adjacent benzene ring, the mean plane of the indoline ring system and the phenyl ring. The mol­ecular structure is stabilized by intra­molecular C—H...O hydrogen bonds. In the crystal, mol­ecules are linked into chains along [101] by N—H...O hydrogen bonds. C—H...π inter­actions are observed between the chains.
