In the title sulfonamide derivative, C(14)H(13)F(2)NO(4)S, the dihedral angle between the benzene rings is 66.05 (9)°. The crystal structure is stabilized by weak inter-molecular N-H⋯O hydrogen bonds involving the amine and meth-oxy groups, which link the mol-ecules into a one-dimensional chain. No significant inter-chain contacts are observed.

In the title compound, C(15)H(15)N(5)O(4)S, the dihedral angle between the pyrimidine and benzene rings is 84.56 (2)°. Intra-molecular hydrazine-carbonyl N-H⋯O and inter-molecular sulfonamide-pyridimine N-H⋯N hydrogen bonds stabilize the mol-ecular and crystal structures, respectively.

The title compound, C15H24N2O2S, was synthesized via a substitution reaction between the enanti-opure (1S,2S)-(+)-1,2-di-amino-cyclo-hexane and 2,4,6-tri-methyl-benzene-1-sulfonyl chloride. The cyclo-hexyl and phenyl substituents are oriented gauche around the sulfonamide S-N bond. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains propagating along [100].

A novel series of carbamothioylamino-benzene-sulfonamide-thiophene-carboxylates 4a-c and thieno[3,2-d]pyrimidin-2-yl-amino-benzene-sulfonamides 5a-c were synthesized in a series of synthetic steps and were used as key intermediates for the synthesis of thienotriazolopyrimidine-benzene-sulfonamide derivatives 6a-c and 7a-c. Thieno[3,2-d]pyrimidinones (8 and 9) were also prepared. Compound 9 was ...

In the crystal, mol-ecules are linked into supra-molecular tubes parallel to [001] by amine-amide N-H⋯O inter-actions and these are conne...

In the title compound, C(14)H(12)ClNO(3)S·H(2)O, the dihedral angle between the sulfonyl and benzoyl benzene rings is 84.4 (2)°. In the crystal, every water mol-ecule forms four hydrogen bonds with three different mol-ecules of 4-chloro-N-(3-methyl-benzo-yl)benzene-sulfonamide. One of the water H atoms forms a bifurcated hydrogen bond with both the sulfonyl and the carbonyl O atoms of the same ...
