1-(4-Methoxyphenyl)-4-(4-methylphenyl)-3-phenoxyazetidin-2-one
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-acti...

In the title compound, C(16)H(12)BrNO(3), the butyrolactone core adopts the furan-2(5H)-one structure and forms dihedral angles of 44.80 (17) and 65.73 (18)° with the bromo-benzene and phenol rings, respectively. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules, generating R(4) (3)(26) loops The edge-fused rings extend to form a chain running along the b-axis direction and C-H...

In the title compound, C(15)H(12)BrNO(2)S, the dihedral angle between the two aromatic rings is 87.81 (8)°. The five-membered thia-zolidine ring has an envelope conformation, with the S atom displaced by 0.4545 (7) Å from the mean plane of the other four ring atoms. The crystal structure exhibits O-H⋯O, C-H⋯O, C-H⋯Br and C-H⋯ π inter-actions.

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-ecule...
متن کامل2-(4-Fluoroanilino)-3-(2-hydroxyethyl)quinazolin-4(3H)-one
The mol-ecular and crystal structures of the title compound, C(16)H(14)FN(3)O(2), are stabilized by intra-molecular N-H⋯O and inter-molecular O-H⋯O hydrogen bonds. The existence of non-classical intra-molecular C-H⋯N hydrogen bonds provides a dihedral angle between the fluoro-substituted benzene and pyrimidinone rings of 7.9 (1)°.
