A series of novel benzosuberone derivatives were synthesized and evaluated as antimicrobial agents by using substituted benzosuberone derivatives 1a,b as starting materials. Treatment of 1a,b with phenyl isothiocyanate in dimethylformamide was followed by treatment with cold HCl solution to afford the thioamides 4a,b, which was reacted with methyl iodide to obtain methylated products 5a,b. Cycl...

Thioamides and selenoamides are better hydrogen-bond donors than carboxamides because their amino groups more positively charged. Quantum chemical analyses reveal that this counterintuitive phenomenon, which cannot be explained by the electronegativity, originates from larger electronic density flow nitrogen lone pair of NH2 group towards lower-lying π* orbital on C=S or C=Se bond. This differe...

Mixed ligand nickel (II), complexes of 2, 2 bipridyle and thioamides 2-aminopyridine, 2-aminoadinine, 2-aminoguanine 2-aminocytocine were prepared. The success synthesis was confirmed through physical spectral characterization on the basis IR NMR spectroscopy, antimicrobial antitumour studies. synthesized compounds found to be active against tested three bacterial strains (Pseudomanas auruginos...

In the title compound, C(11)H(14)N(2)OS, the thioamide C=S and amide C=O bonds are anti to each other; the N-H bonds are also anti to each other. The mol-ecular conformation is stabilized by an N-H⋯O hydrogen bond. In the crystal, the mol-ecules are linked into inversion dimers by pairs of N-H⋯S hydrogen bonds.

Ketones smoothly reacted with NBS in the presence of a catalytic amount of p-toluenesulfonic acid to give α-bromoketones in good yields in typical ionic liquids, such as [bmim]PF6 and [bmpy]Tf2N, and the ionic liquids could be repeatedly used for the same reaction after the extraction of the α-bromoketones. Then, the one-pot conversion of ketones into thiazoles by the treatment with NBS, and su...
