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

ABSTRACT: The central ?-lactam ring of the title compound, C(23)H(21)NO(3), is almost planar (r.m.s. deviation = 0.032Å). The meth-oxy-benzene ring is almost coplanar with the ?-lactam ring [dihedral angle = 1.87?(11)°], whereas the tolyl ring is almost normal to it [75.73?(12)°]. The dihedral angle between the ?-lactam ring and the O-bonded phenyl ring is 51.95?(12)°. An intra-molecular C-H?O inter-action generates an S(6) ring. The crystal structure features inter-molecular C-H?O hydrogen bonds, forming layers parallel to (011), and weak C-H?? inter-actions. Two aromatic ?-? stacking inter-actions [centroid-centroid distances = 3.6744?(12) and 3.6799?(11)?Å] are also observed.

The central β-lactam ring of the title compound, C(23)H(21)NO(3), is almost planar (r.m.s. deviation = 0.032Å). The meth-oxy-benzene ring is almost coplanar with the β-lactam ring [dihedral angle = 1.87 (11)°], whereas the tolyl ring is almost normal to it [75.73 (12)°]. The dihedral angle between the β-lactam ring and the O-bonded phenyl ring is 51.95 (12)°. An intra-molecular C-H⋯O inter-action generates an S(6) ring.

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

Project description:In the title compound, C(22)H(18)N(2)O(5), the four-membered β-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⋯π stacking inter-actions. Furthermore, a π-π inter-action [centroid-centroid distance = 3.6129 (19) Å] helps to stabilize the crystal structure.

Project description:In the title compound, C(22)H(17)ClN(2)O(5), the nearly planar four-membered β-lactam ring [maximum deviation of 0.016 (1) for the N atom] makes dihedral angles of 53.07 (9), 73.19 (9) and 6.61 (9)° with the chloro-, nitro- and meth-oxy-benzene rings, respectively.

Crystal structure of 1-(4-meth-oxy-phen-yl)-4-(4-nitro-phen-yl)-3-phen-oxy-azetidin-2-one.

Project description:In the title compound, C22H18N2O5, the central β-lactam ring (r.m.s. deviation = 0.002 Å) makes dihedral angles of 64.21 (14), 82.35 (12) and 20.66 (13)° with the phenyl ring and the nitro- and meth-oxy-benzene rings, respectively. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming slabs lying parallel to (111). The slabs are linked via C-H⋯π inter-actions, forming a three-dimensional network.

2-Meth-oxy-imino-2-{2-[(2-methyl-phen-oxy)meth-yl]phen-yl}ethanol.

Project description:In the title compound, C(17)H(19)NO(3), the dihedral angle between the benzene rings is 68.0 (1)°. The C-O-C-C torsion angle of the atoms joining these rings is 179.7 (2)°. The atoms of the methanol group were refined as disordered over two sets of sites with fixed occupancies of 0.86 and 0.14. The H atoms of the hy-droxy group in the major component are disordered over a further two sets of sites with equal occupancies. This is a necessary arrangement to allow for hydrogen bonding without unrealistic H⋯H contacts. In the crystal, O-H⋯N and O-H⋯O hydrogen bonds connect mol-ecules into chains along [001].

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 β-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.

3,3-Bis[(4-meth-oxy-phen-yl)sulfan-yl]-1-methyl-piperidin-2-one.

Project description:The piperidone ring in the title compound, C(20)H(23)NO(3)S(2), has a distorted half-chair conformation with the central methyl-ene atom of the propyl fragment lying 0.696 (1) Å out of the plane defined by the other five atoms (r.m.s. deviation = 0.071 Å). One of the S-bound phenyl rings is almost perpendicular to the mean plane through the piperidone ring, whereas the other is splayed [dihedral angles = 71.95 (6) and 38.42 (6)°]. In the crystal, C-H⋯O and C-H⋯π inter-actions lead to the formation of supra-molecular layers in the ab plane.

Project description:In the title compound, C(17)H(17)NO(4), the dihedral angle between the two aromatic rings is 59.64?(5)°. The (meth-oxy-imino)-ethanoic acid fragment is nearly perpendicular to the attached benzene ring [dihedral angle = 81.07?(4)°]. In the crystal, pairs of O-H?O hydrogen bonds between carb-oxy groups link mol-ecules into inversion dimers. In addition, ?-? stacking inter-actions between inversion-related benzene rings are observed [centroid-centroid distance = 3.702?(1)?Å].
