1-(4-Meth-oxy-phen-yl)-4-(3-nitro-phen-yl)-3-phen-oxy-azetidin-2-one.

ABSTRACT: In the title compound, C(22)H(18)N(2)O(5), the four-membered ?-lactam ring is nearly planar, with a maximum deviation of 0.023?(2)?Å for the N atom, and has long C-C distances of 1.525?(5) and 1.571?(5)?Å. The mean plane of this group makes dihedral angles of 11.61?(19), 74.5?(2) and 72.3?(2)° with three aromatic rings. An intra-molecular C-H?O hydrogen bond occurs. The packing of the mol-ecules in the crystal structure is governed mainly by inter-molecular C-H?O hydrogen-bonding and C-H?? stacking inter-actions. Furthermore, a ?-? inter-action [centroid-centroid distance = 3.6129?(19)?Å] helps to stabilize the crystal structure.

Azetidin-2-ones: structures of anti-mitotic compounds based on the 1-(3,4,5-tri-meth-oxy-phen-yl)azetidin-2-one core.

Project description:A series of related substituted 1-(3,4,5-tri-meth-oxy-phen-yl)azetidin-2-ones have been characterized: 3-(4-fluoro-phen-yl)-4-(4-meth-oxy-phen-yl)-1-(3,4,5-tri-meth-oxy-phen-yl)azetidin-2-one, C25H24FNO5 (1), 3-(furan-2-yl)-4-(4-meth-oxy-phen-yl)-1-(3,4,5-tri-meth-oxy-phen-yl)azetidin-2-one, C23H23NO6 (2), 4-(4-meth-oxyphen-yl)-3-(naphthalen-1-yl)-1-(3,4,5-tri-meth-oxy-phen-yl)azetidin-2-one, C29H27NO5 (3), 3-(3,4-di-meth-oxy-phen-yl)-4-(4-meth-oxy-phen-yl)-1-(3,4,5-tri-meth-oxy-phen-yl)azetidin-2-one, C27H29NO7 (4) and 4,4-bis-(4-meth-oxy-phen-yl)-3-phenyl-1-(3,4,5-tri-meth-oxy-phen-yl)azetidin-2-one, C32H31NO6 (5). All of the compounds are racemic. The lactam and 3,4,5-tri-meth-oxy-phenyl rings are approximately co-planar and the orientation of the lactam and the 4-meth-oxy-phenyl substituent is approximately orthogonal. The chiral centres, although eclipsed by geometry, have torsion angles ranging from -7.27 to 13.08° for the 3 position, and -8.69 to 13.76° for the 4 position of the ?-lactam. The structures display intra-molecular C-H?O bonding between the 3,4,5-tri-meth-oxy-phenyl ring and the lactam ketone. Further C-H?O inter-actions are observed and form either an opposing meth-oxy 'buckle' to join two mol-ecules together or a cyclic dimer.

2-[(4-Meth-oxy-2-nitro-phen-yl)imino-meth-yl]phenol.

Project description:The crystal structure of the title compound, C(14)H(12)N(2)O(4), contains four crystallographically independent mol-ecules in the asymmetric unit. All the mol-ecules have similar conformations; the dihedral angles between the aromatic rings are 33.1?(1), 33.76?(9), 31.41?(9) and 32.56?(10)°.
