Thiazinones containing sulfonamides are experiencing increased interest due to their importance in the design and development of new molecules potential pharmaceutical interest. The synthesis a series Nsubstituted 2H-1,3-thiazin-2-ones sulfonamide is described. compounds were synthesized good yields one-pot reaction starting from commercially available chlorosulfonyl isocyanate (CSI), 3chloro-1...

In the title compound, C15H23N3O3S·H2O, the piperidine ring has a chair conformation. In the crystal, the sulfonamide mol-ecules are linked by N-H⋯O hydrogen bonds, forming a layer parallel to (10-1). The layers are inter-connected via N-H⋯Ow, Ow-H⋯N and Ow-H⋯O (w = water) hydrogen bonds, forming a three-dimensional network.

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].

In the title compound, C(7)H(6)ClN(3)O(4)S(2)·3C(5)H(5)N, (systematic name: 6-chloro-2H-1,2,4-benzothia-diazine-7-sulfonamide 1,1-dioxide pyridine tris-olvate), chloro-thia-zide forms a 1:3 solvate with pyridine. The crystal structure is stabilized by strong inter-molecular N-H⋯N hydrogen bonds.

The title compound, C(13)H(19)NO(2)S, was synthesized by the reaction of N-cyclo-hexyl-amine-benzene-sulfonamide and methyl iodide. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

The title co-crystal [systematic name: 3-(1,3-dioxoisoindolin-2-yl)propanoic acid-1,3,7-trimethyl-1H-purine-2,6(3H,7H)-dione (1/1)], C(8)H(10)N(4)O(2)·C(11)H(9)NO(4), is the combination of 1:1 adduct of N-phthaloyl-β-alanine with caffeine. The phthalimide and purine rings in the N-phthaloyl-β-alanine and caffeine mol-ecules are essentially planar, with r.m.s. deviations of the fitted atoms of 0...

A new series of aromatic and heterocyclic sulfonamides, including six new derivatives, 2-(3-cyclohexene-1-carbamido)-1,3,4-thiadiazole-5-sulfonamide (CCTS), 4-(3-cyclohexene-1-carbamido) methyl-benzenesulfonamide (CCBS), 2-(9-octadecenoylamido)-1,3,4-thiadiazole-5-sulfonamide (ODTS), 2-(4,7,10-trioxa-tetradecanoylamido)-1,3,4-thiadiazole-5-sulfonamide (TDTS), 2-(coumarine-3-carbamido)-1,3,4-thi...
