Methyl 8-bromo-3-1-(4-meth­oxy­phen­yl)-4-oxo-3-phenyl­azetidin-2-yl-1-methyl-1233a49b-hexa­hydro­chromeno43-bpyrrole-3a-carboxyl­ate

摘要

In the title compound, C30H29BrN2O5, the β-lactam ring is essentially planar, with the O atom displaced from this plane by 0.856 (9) Å, and forming dihedral angles of 24.35 (13) and 89.42 (14)° with the planes of the benzene substituent groups on this ring. The tetra­hydro­pyran ring adopts an envelope conformation with the C atom bearing the β-lactam ring as the flap. In the crystal, weak C—H⋯O hydrogen bonds with carboxyl and tetra­hydro­pyran O-atom acceptors give rise to a chain structure extending along the b-axis direction.
