Ethyl 1-(4-chlorophenyl)-3-[1-(4-methoxyphenyl)-4-oxo-3-phenylazetidin-2-yl]-2-nitro-2,3,10,10a-tetrahydro-1H,5H-pyrrolo[1,2-b]isoquinoline-10a-carboxylate

Abstract: In the title compound, C₃₇H₃₄ClN₃O₆, the pyrrolidine and piperidine rings adopt envelope and boat conformations, respectively. The -lactam ring is planar and forms dihedral angles of 21.3 (2) and 73.9 (2)°, respectively, with the attached methoxyphenyl and phenyl rings. Intramolecular C-HO and C-HN hydrogen bonds are observed. Centrosymmetrically related molecules are linked together by weak C-HO hydrogen bonds to form dimers.
