In the title ester derivative, C28H29NO6·0.5H2O, the 1,4-dihydro-pyridine ring has a flattened boat conformation. The mean plane is almost perpendicular to the attached benzene ring, making a dihedral angle of 86.87 (9)°. The terminal phenyl ring is inclined to the central benzene ring by 67.56 (12)°. In the crystal, mol-ecules are bridged via O-H⋯O… (More)
In the title compound, C18H19BrO4, the aromatic rings enclose a dihedral angle of 81.9 (7)°. There are no short directional contacts in the crystal structure.
In the title compound, C32H25NO5, the furan and pyrrole rings each adopt an envelope conformation, the respective flap atoms being the C atom bearing the pyrene substituent and the CH2 atom adjacent to the N atom. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond. In the crystal, C-H⋯O contacts link the mol-ecules, forming… (More)
To meet changing demands in the business process, multiple services have to be combined. Service Oriented Architecture offers Service Composition mechanisms, using which various services can be combined or composed according to user requirements. The services are combined in static and dynamic manner. The dynamic service composition approaches are moving… (More)
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 tetra-hydro-pyran ring adopts an envelope conformation with the C atom bearing the β-lactam ring… (More)
In the title compound C(14)H(17)N(3)O(2), the dihedral angle between the rings is 16.68 (13)°. Although the compound crystallizes in the keto form, the possibility of keto-enamine-enol-imine tautomerism is explained by a strong intra-molecular N-H⋯O hydrogen bond.
