Crystal Structure, Energy Minimization and Geometry Optimization Studies of 5-bromo-1- Ethyl-indoline-2,3-dione
Isatin (1H-indole-2,3-dione) is an endogenous compound that has been identified in humans and possesses a wide range of biological activities, such as anxiogenic and sedative activities. A variety of biological activities are associated with isatin, including central nervous system (CNS) activities (Raj, 2012). The single crystal X-ray diffraction study of the title compound has been made and i...
متن کامل3-Ethyl-2-(ethylimino)-4-methyl-2,3-dihydro-1,3-thiazole-5-carboxylate Ethyl Ester
An efficient procedure to obtain the new compound 1a from ethyl acetoacetate (2a), NBS and N,N′-diethylthiourea (4a) was reported. In comparison with the traditional method to synthesize its analogues, this efficient, catalyst-free, and one-pot synthetic method is facile. The work-up procedure is easy and gives the pure target compound under milder reaction conditions in a relatively high yield...
متن کاملCrystal structure of tetraaquabis(1,3-dimethyl-2,6-dioxo-7H-purin-7-ido-κN 7)cobalt(II)
The title complex, [Co(C7H7N4O2)2(H2O)4], comprises mononuclear mol-ecules consisting of a CoII ion, two deprotonated theophylline ligands (systematic name: 1,3-dimethyl-7H-purine-2,6-dione) and four coordinating water mol-ecules. The CoII atom lies on an inversion centre and has a slightly distorted octa-hedral coordination environment, with two N atoms of two trans-oriented theophylline ligan...
متن کاملCrystal structure of ethyl 2-({[(4Z)-3,5-dioxo-1-phenylpyrazolidin-4-ylidene]methyl}amino)acetate
The title compound, C14H15N3O4, is nearly planar, the dihedral angle between the planes of the phenyl and pyrazolidine rings being 1.13 (7) Å, and that between the plane of the pyrazolidine ring and the mean plane of the side chain [C-N-C-C(=O)-O; r.m.s. deviation = 0.024 Å] being 2.52 (7)°. This is due in large part to the presence of the intra-molecular N-H⋯O and C-H⋯O hydrogen bonds. In the ...

In the title compound, C23H22N2O4S, the pyrrolidine ring has an envelope conformation with the spiro C atom, shared with the indoline ring system, as the flap. The mean planes of the benzo-thio-phene and indoline ring systems are inclined to the mean plane of the pyrrolidine ring by 88.81 (8) and 79.48 (8)°, respectively, and to each other by 68.12 (5)°. In the crystal, mol-ecules are linked vi...
