(1S,3′S,3a′R,6′S)-6′-(2-Chlorophenyl)-3′-[(2R,3S)-1-(4-methoxyphenyl)-4-oxo-3-phenylazetidin-2-yl]-2-oxo-3′,3′a,4′,6′-tetrahydro-2H,2′H-spiro[acenaphthylene-1,1′-pyrrolo[1,2-c][1,3]thiazole]-2′,2′-dicarbonitrile

Abstract

The mol­ecular conformation of the title compound, C41H29ClN4O3S, is stabilized by intra­molecular C—H⋯O and C—H⋯Cl hydrogen bonds. The thia­zole ring adopts an envelope conformation with the N atom as the flap, while the pyrrolidine ring has a twisted conformation on the N—C bond involving the spiro C atom. The β la­ctam ring makes dihedral angles of 39.74 (15) and 16.21 (16)° with the mean planes of the thia­zole and pyrrolidine rings, respectively. The thia­zole ring mean plane makes dihedral angles of 23.79 (13) and 70.88 (13) ° with the pyrrolidine and cyclo­pentane rings, respectively, while the pyrrolidine ring makes a dihedral angle of 85.63 (13)° with the cyclo­pentane ring. The O atom attached to the β la­ctam ring deviates from its mean plane by 0.040 (2) Å, while the O atom attached to the cyclo­pentane ring deviates from its mean plane by 0.132 (2) Å. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming chains along [010], and C—H⋯π and π-π inter­actions [centroid-centroid distance = 3.6928 (17) Å].
