Parkinson's disease is a neurodegenerative disorder that involves the degeneration of nigrostriatal dopaminergic neurons. Elevated levels of reactive oxygen species have been shown to deplete cellular levels of the ubiquitous antioxidant glutathione, lead

1,2-Dithiole-3-thione (1) react with a number of selected α,β-unsaturated nitriles to give thiopyrano[2,3-b]pyrane (3 a,b) and /or pyridine (3c) derivatives in excellent yields. The products result from a ring-opening ring-closure reaction and a concomita

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
1,1'2,2'-Tetrathiafulvalenes, III. - Syhthesis, Properties, and Reactions of 3,3'-Bi(3H-1,2-dithiolylidenes)(1,1',2,2'-Tetrathiafulvalenes)

1,1',2,2'-tetrathiafulvalenes 1 can be prepared by different methods from the cations of 1,2-dithiolylium salts 4 which are either unsubstituted or appropriate substituted in 3-position (instead of 3-Cl also H or SCH3).The structure of 1 is substantiated by chemical arguments.IR and 13C-NMR spectra support the absence of thioxo groups. - Like the 1,1',3,3'-isomers 2 the 1,1',2,2'-tetrathiafulvalenes are disposed to stepwise donation of electrons with formation of the radical cation and dication salts 25 or 11, respectively, as well as to the formation of charge transfer complexes with tetracyanoethylene, tetracyanoquinodimethane, and 2,3-dichloro-5,6-dicyanobenzoquinone.Tris(triphenylphosphine)rhodium(I) chloride and tetrakis(triphenylphosphine)platinum(O) yield complexes with 1a. - Thermolysis of 1 produces thienothiophenes 6.Partial desulfuration of 1a, for example, is also feasible with oxidizing agents like lead(IV) acetate.Selenium dioxide, however, gives the corresponding thienofuran 41.The reaction with trialkyl phosphites yields a disulfide - probably the 2,2'-bi(2H-thietylidene) 38 - the thermolysis of which gives the thienothiophene 6a. - Compounds 1a and 1c do not react with dimethyl acetylenedicarboxylate, isothiocyanate, several 1,3-dipoles (azides), and also not with elementary sulfur, however, 1e forms with sulfur the 3H-1,2-dithiol-3-thione 5e (X = S).
