In the title compound, C17H21N2O6P·CH3OH, the planes of the 4-nitro-aniline and 2-hy-droxy-phenyl groups form a dihedral angle of 84.04 (8)°. The P atom exhibits tetra-hedral geometry involving two O-ethyl groups, a Cα atom and a double-bonded O atom. In the crystal, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds link the α-amino-phospho-nic acid and methanol mol-ecules into chains that propagate parall...

Chemicals-o-Aminophenyl glucosiduronic acid was kindly supplied by Dr. R. T. Williams, St. Mary’s Hospital Medical School, London. oAminobenzoyl and p-aminobenzoyl glucosiduronic acids were prepared enzymatically with UDP-glucuronic acid’ and aglycone (5). Phenolphthalein glucosiduronic acid and bacterial P-glucuronidase were obtained from the Sigma Chemical Company, St. Louis, Missouri. UDP-gl...
The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicy...
The title compound, C(20)H(18)N(2)O, is composed of three aromatic rings, the dihedral angles between the phenyl and benzamide rings, and between the benzamide and aniline rings being 59.86 (9) and 46.57 (10)°, respectively. The mol-ecular structure is stabilized by an intra-molecular N-H⋯O hydrogen bond involving the amino H atom and the benzamide carbonyl O atom. In the crystal structure, C-H...
The asymmetric unit of the title compound, C(9)H(11)NO·C(6)H(5)N(3)O(4), contains two independent mol-ecules each of 4-(dimethyl-amino)-benzaldehyde and 2,4-dinitro-aniline. In the crystal, the components are linked by inter-molecular N-H⋯O hydrogen bonds to form one-dimensional chains along [10[Formula: see text]]. Intra-molecular N-H⋯O hydrogen bonds are also present.
The crystal structure of the title compound, C(14)H(15)NO·0.5H(2)O, features N-H⋯O and O-H⋯N hydrogen bonds between the amino group and water molecule of crystallization, which generate a chain along the c axis. The water mol-ecule lies on a twofold rotation axis. A C-H⋯π inter-action is observed between the phenyl and aniline rings. The angle between the mean planes of the phenyl rings is 72.5...
The title compound, C(34)H(35)O(2)N(3), was synthesized by the reaction of 2-[3,6-bis-(diethyl-amino)-9H-xanthen-9-yl]benzoyl chloride with aniline. In the mol-ecular structure, the dihedral angles between the isoindoline and xanthene planes and between the isoindoline and benzene planes are 86.9 (3) and 47.0 (2)°, respectively. The mol-ecular packing in the crystal structure is stabilized by w...
Cyclization and chlorination of 2-amino-5-benzyl-4, 5, 6, 7-tetrahydro hydro thieno [3, 2c] pyridine-3carboxamide yielded (3 a-b). Reaction with different substituted pyridines of [3 a-b] yielded 4a (1-4) and 4b (1-2). However reaction of 3a with different substituted 2-amino phenols yielded 4a (5-6). Further 3a yields 4a (7) & 4a (8) from different substituents like o-phenylene diamine and 4-c...
