In the present work, two new potentially active quinazolin-4-yl-aminobenzenesulfonamide
derivatives, N-(5-methyl-1, 2-oxazol-3-yl)-4-[(quinazolin-4-yl) amino] benzene-1 …

Fifty four N-(i, j-disubstituted phenyl)-4-substituted benzenesulphonamides of the general
formula 4-X'C6H4SO2NH (i, j-X2C6H3), where X'= H, CH3, C2H5, F, Cl or Br; i, j= 2, 3; 2, 4; …

In the title compound, C 13 H 13 NO 2 S, the dihedral angle between the aromatic rings is
68.4 (1). In the crystal, the molecules are linked into inversion dimers by pairs of N—H⋯ O …

In the crystal structure of the title compound, C14H15NO2S, the N—H bond is trans to one of
the S= O double bonds, similar to what is observed in N-(2-methylphenyl) …

In the crystal structure of the title compound, C12H10ClNO2S, the N—H bond is trans to one
of the S= O bonds. The two aromatic rings form a dihedral angle of 65.4 (1)°, compared with …

In the title compound, C13H13NO2S, the conformation of the N—H bond is anti to the ortho-
methyl group on the aniline ring, in contrast to the syn conformation observed with respect to …

In the crystal structure of the title compound, C14H15NO2S, the amino H atom is trans to one
of the O atoms of the SO2 group. Furthermore, the N—H bond is anti to the ortho-and meta …

Two recent projects described approaches to 1, 1-dimethyl-1, 2, 3, 4-
tetrahydronaphthalenes1 and 4, 4-dimethyl-1, 2, 3, 4-tetrahydroisoquinolines2 using acid …

In the title compound, C18H18Cl2N2O6S2, the asymmetric unit contains half a molecule
with a center of symmetry at the mid-point of the central C—C bond. The dihedral angle …

In title compound, C14H12N2O5S, the dihedral angle between the sulfonyl benzene ring
and the—SO2—NH—C—O segment is 81.5 (2)° and that between the sulfonyl and the …
