N-(4-Amino-phen-yl)-1,8-naphthalimide hemihydrate.

ABSTRACT: The title compound, C(18)H(12)N(2)O(2)·0.5H(2)O, was prepared by the reaction of 1,4-phenyl-enediamine with 1,8-naphthalic anhydride in refluxing dimethyl-formamide. The structure is stabilized by N-H?O and O-H?O hydrogen bonds. There are ?-? stacking inter-actions [centroid-centroid distances of 3.718?(2), 3.510?(2) and 3.546?(2)?Å] and C-H?? inter-actions between the mol-ecules. The water molecule lies on a twofold rotation axis. Its two H atoms are disordered equally over two positions.

The title compound, C(18)H(12)N(2)O(2)·0.5H(2)O, was prepared by the reaction of 1,4-phenyl-enediamine with 1,8-naphthalic anhydride in refluxing dimethyl-formamide. The structure is stabilized by N-H⋯O and O-H⋯O hydrogen bonds. There are π-π stacking inter-actions [centroid-centroid distances of 3.718 (2), 3.510 (2) and 3.546 (2) Å] and C-H⋯π inter-actions between the mol-ecules. The water molecule lies on a twofold rotation axis. Its two H atoms are disordered equally over two positions. ...[more]

N-Methacryloyl-4-(piperidin-1-yl)-1,8-naphthalimide.

Project description:In the title compound, C(21)H(20)N(2)O(3), the naphthalimide unit is almost planar (r.m.s. deviation for the 15 non-H atoms = 0.059?Å). The carboximide N atom and the five C atoms of the 2-methyl-prop-2-enoyl substituent also lie in a plane (r.m.s. deviation = 0.009?Å), which subtends an angle of 84.34?(7)° to the naphthalamide plane. This orients the =CH(2) group of the vinyl fragment towards the naphthalimide rings, giving the mol-ecule an extended configuration. The piperidine ring adopts a chair conformation and there is evidence for some delocalization between the naphthalene and piperidine units, the C-N(pip) bond length being 1.404?(4)?Å. In the crystal structure, ?-? contacts with centroid-centroid distances of 3.5351?(18) and 3.7794?(18)?Å supported by C-H?O hydrogen bonds link adjacent mol-ecules in a head-to-tail fashion, forming dimers. These are further stabilized by other C-H?O contacts of varying strength, which stack the mol-ecules down the b axis.

Methyl 2-{[(4-hydroxy-phen-yl)(methoxy-carbon-yl)meth-yl]amino-carbon-yl}ethano-ate hemihydrate.

Project description:In the structure of the title compound, C(13)H(15)NO(6)·0.5H(2)O, the water O atom lies on a twofold rotation axis. The methoxy-carbonyl-methyl and amino groups are essentially coplanar and the methoxy-carbonyl-methyl group makes a dihedral angle of 79.73 (10)° with the mean plane of the hydroxy-phenyl ring. The amino and methoxy-carbonyl-methyl groups are involved in an intra-molecular N-H⋯O hydrogen bond which generates an S(5) ring motif. In the crystal structure, mol-ecules are linked via N-H⋯O and O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions into a two-dimensional network parallel to the (01) plane. The crystal structure is further stabilized by C-H⋯π inter-actions.

Photosensitized Oxidative Dimerization at Tyrosine by a Water-Soluble 4-Amino-1,8-naphthalimide.

Project description:The oxidation of proteins generates reactive amino acid (AA) residue intermediates, leading to protein modification and cross-linking. Aerobic studies with peptides and photosensitizers allow for the controlled generation of reactive oxygen species (ROS) and reactive AA residue intermediates, providing mechanistic insights as to how natural protein modifications form. Such studies have inspired the development of abiotic methods for protein modification and crosslinking, including applications of biomedical importance. Dityrosine linkages derived from oxidation at tyrosine (Tyr) residues represent one of the more well-understood oxidation-induced modifications. Here we demonstrate an aerobic, visible light-dependent oxidation reaction of Tyr-containing substrates promoted by a water-soluble 4-amino-1,8-naphthalimide-based photosensitizer. The developed procedure converts Tyr-containing substrates into o,o'-Tyr-Tyr linked dimers. The regioselectively formed o,o'-Tyr-Tyr linkage is consistent with dimeric standards prepared using a known enzymatic method. A crossover study with two peptides provides a statistical mixture of three distinct o,o'-Tyr-Tyr linked dimers, supporting a mechanism that involves Tyr residue oxidation followed by intermolecular combination.

The attached benzene ring of the 4-chloro-phenyl substituent is inclined to the mean plane of the naphthalimide ring system by 75.77?(11)°.

[1-(3-Chloro-phen-yl)-1H-1,2,3-triazol-4-yl]methanol hemihydrate.

Project description:The asymmetric unit of the title hydrate, C(9)H(8)ClN(3)O·0.5H(2)O, comprises two independent 1,2,3-triazole mol-ecules and a water mol-ecule of crystallization. The dihedral angles between the six- and five-membered rings in the 1,2,3-triazole mol-ecules are 12.71?(19) and 17.3?(2)°. The most significant different between them is found in the relative orientations of the terminal CH(2)OH groups with one being close to perpendicular to the five-membered ring [N-C-C-O torsion angle = 82.2?(5)°], while in the other mol-ecule, a notable deviation from a perpendicular disposition is found [torsion angle = -60.3?(5)°]. Supra-molecular chains feature in the crystal packing sustained by O-H?(O,N) inter-actions along the a-axis direction. The chains are connected via C-H?N inter-actions and the resultant layers stack along the b axis.
