It has been reported that microsomal metabolism of ADT (5-(p-methoxyphenyl)-3H-1,2-dithiole-3-thione, anetholedithiolethione, Sulfarlem) and ADO (5-(p-methoxyphenyl)-3H-1,2-dithiole-3-one, anetholedithiolone) led to formation of H2S mainly deri

A simple and practical strategy for the preparation of 1,2-dithiole-3-thiones via copper-catalyzed defluorinative thioannulation of trifluoropropynes has been developed using elemental sulfur as the sole sulfur source. This reaction displays a wide substrate scope and high functional group tolerance to afford the corresponding S-heterocycles in moderate to good yields and features efficient construction of multiple C?S bonds through C?F bond cleavage of CF3 groups.

Thioaroylketene S,N-acetals were treated with active methylene compounds including β-keto ester, nitromethane, cyanoacetic acid, p- toluenesulfonylacetone, 4-nitrophenylacetic acid, and diethyl (2- oxopropyl)phosphonate in the presence of mercury(II) acetate in CH2Cl2 at room temperature. These reactions gave 3-alkylamino-5-arylthiophenes containing various substituents, which comprised, respectively, alkoxycarbonyl, nitro, cyano, p-toluenesulfonyl, 4-nitrophenyl, and diethylphosphono groups at C-2 in good yields. The reaction of 3-methylamino- 3-methylthio-1-phenylthioxopropene with malonic acid or Meldrum's acid under the same conditions gave 3-methylamino-5-phenylthiophene. Similarly, treatment of 3-methylamino-3-methylthio-1-phenylthioxopropene with various enolizable cyclic ketones such as 4-hydroxy-6-methyl-2-pyrone, homophthalic anhydride, 2-hydroxy1,4-benzoquinone, and 1,3-diethyl-2-thiobarbituric acid gave thieno[3,2-b]pyridin-4-one, thieno[3,2c]isoquinolin-5-one, thieno[3,2- c]benzazepine-1,6-dione, and thieno[3,2-d]pyrimidine-2,4-dione, respectively.

The synthesis of N2S2 tetradentate ligands of the bis-(enaminothioester) type was carried out starting from 3-(methylthio)-3H-1,2-dithiolylium iodides and diamines.The title compounds, which are potential ligands for soft cationic species, can be obtained from 1,3-diaminopropan-2-ol and subsequently modified into the dissymmetrical succinic acid ester of the ligand and N-hydroxysuccinimide.The appendage of such a linking group on the chelating structure should allow further grafting to monoclonal antibodies in view of potential applications in nuclear medicine. 3H-1,2-dithiole-3-thione / 1,3-diaminopropan-2-ol / bis-(enaminothioester) / N2S2 tetradentate ligand / N-hydroxysuccinimidyl ester
Use of carbon-sulfur cathodes in electro-organic chemistry - Part 2 - Reactions with activated alkenes; evidence for a vicarious substitution specific of this type of electrode.

The sulfur-carbon electrode, used as a cathode, appears to be an excellent source of nucleophiles which are good sulfuration reagents towards alkenes not substituted by leaving groups.However, the electrochemical reactions are often complex.It should be w

3-Chloro-5-phenyl-1,2-dithiolylium chloride condenses in ethanol with 2-amino-N-heterocycles at the amino-group to yield yellow compounds; in many instances reaction occurs also at the ring nitrogen atom yielding orange compounds. 2-Amino-Δ2-thiazoline, 2-aminothiazole, 2-aminopyridine and its monomethyl derivatives, 2-amino-4,6-dimethylpyridine ,2-aminopyrimidine, and 2-aminobenzimidazole all underwent reaction at the amino-group to give the corresponding yellow 2-(5-phenyl-1,2-dithiol-3-ylidenamino)-N-heterocycles. 2-Amino-Δ2-thiazoline, 2-aminothiazole, 2-aminopyridine, 2-amino-3-methylpyridine, 2-amino-4-methylpyridine,and 2-amino-5-methylpyridine also underwent reaction at the ring nitrogen atom to give in low yield 4,5-dihydro-3-thiobenzoylmethylene-3H -thiazolothiadiazole, 3-thiobenzoylmethylene-3H-thiazolothiadiazole, and 3-thiobenzoylmethylene-3H-pyridothiadiazole and its 7-,6-,and 5-methyl derivatives, respectively,as polar orange compounds.The condensations of 3-methoxy-5-phenyl-1,2-dithiolylium fluorosulphonate with 2-amino-Δ2-thiazoline, 2-aminothiazole, and 2-amino-4-methylpyridine were studied.Condensation of 4-methyl-2-tricloromethylthioaminopyridine with benzoylacetic acid in dimethylformamide in the presence of triethylamine gave 6-methyl-3H-pyridothiadiazol-3-one (main prduct) and 6-methyl-3-benzoylmethylene-3H-pyridothiadiazole.Thionation of the latter with tetraphosphorous decasulphide in pyridine gave 6-methyl-3-thiobenzoylmethylene-3H-pyridothiadiazole.The results of 1H n.m.r. spectral studies, and of X-ray crystallographic studies by other workers, are discussed in relation to the structure of the yellow and the orange series of condesation products.It is proposed that the 3-thiobenzoylmethylene-3H-thiazolothiadiazoles and the 3-thiobenzoylmethylene-3H-pyridothiadiazoles, whose formation involves an S-S -> S-N bond switch, are formed via 3H-6,6aλ4-dithia-1,3-diazapentalenes which are higer energy intermediates or transition states. 3-Chloro-5-phenyl-1,2-dithiolylium chloride condensed with 2,6-diaminopyrimidine in a 2:1 ratio to give an orange and a polar red product for which structures are proposed.
