Diethyl 2-[(5-methoxy-2-methyl-1-phenylsulfonyl-1H-indol-3-yl)methylene]malonate
In the title compound, C(24)H(25)NO(7)S, the sulfonyl-bound phenyl ring is approximately perpendicular to the indole ring system [dihedral angle = 87.72 (5)°]. The methyl group of one of the ester units is disordered over two positions with occupancies of 0.527 (13) and 0.473 (13). An intra-molecular C-H⋯O hydrogen bond is observed. In the crystal structure, mol-ecules are linked into a ribbon ...

4-(acetoacetamido) arsanilic acid (II), which was then condensed with aryl aldehydes. The resulting product on reaction with hydrazine hydrate and hydroxyl amine hydrochloride yielded Pyrazolines (IV) and Isoxazolines (V), respectively. The antimicrobial activity of compounds against a number of microorganisms was evaluated. Some of these compounds showed significant antimicrobial activity
متن کامل5-(4-Chlorophenyl)-1-methyl-3-oxocyclohexanecarbonitrile
In the title mol-ecule, C(14)H(14)ClNO, the cyclo-hexane ring adopts a chair conformation. The cyano group and the methyl group have axial and equatorial orientations, respectively. The benzene ring has an equatorial orientation. A C-H⋯π inter-action involving the benzene ring is found in the crystal structure.

In the title compound, C(23)H(25)NO(5), the lactam ring adopts an envelope conformation and both eth-oxy-carbonyl side chains show an s-cis conformation: one is nearly planar, the dihedral angle between CO(2) and OCH(2)CH(3) groups being 7.95 (14)° and the other is almost orthogonal, the C-O-C-C torsion angle being 85.33 (9)°. Dimers related by inversion symmetry are stabilized by C-H⋯O hydroge...
