11-[1-(4-Methoxyphenyl)-4-oxo-3-phenoxyazetidin-2-yl]-14-methyl-12-oxa-8,14-diazatetracyclo[8.3.3.01,10.02,7]hexadeca-2(7),3,5-triene-9,13-dione

Abstract

In the title compound, C30H27N3O6, the furan and pyrrolidine rings adopt envelope conformations (with C and N atoms as the flaps, respectively). The piperidine ring is in a distorted boat conformation. The β-lactam ring is planar [maximum deviation = 0.0044 (16) Å] and forms dihedral angles of 30.61 (9) and 85.51 (9)°, respectively, with the attached methoxyphenyl and phenoxy rings. The crystal packing is stabilized by N—H...O and C—H...O interactions forming R22(8), R22(20) and R22(14) ring motifs. The crystal structure is further consolidated by weak C—H...π interactions.
