Facile introduction of SH group on aromatic substrates via electrophilic substitution reactions

Herein, we describe a mild and efficient two-step procedure to introduce a thiol group on aromatic substrates. First, reaction with an activated sulfoxide leads to an arylsulfonium salt intermediate. Then, two successive β-elimination-based dealkylation reactions afford the desired arylthiols in good to excellent yields.

EFFICIENT SYNTHESIS AND BIOLOGICAL PROPERTIES OF NEW BENZOPENTATHIEPINS

New 6,7-dimethoxybenzopentathiepin and 6-(2-aminoethyl)benzopentathiepin, which are partial structures of varacin, were synthesized from 1,2-dimethoxybenzene and 1,2-benzenedithiol respectively.

Synthesis and Conformational Analysis of Dibenzodithiocin Derivatives

N-(3,4-Dialkoxyphenylthiomethyl)aroylamides (1a, b) reacted with phosphoryl chloride to give not only the expected 4H- and 2H-1,3-benzothiazine derivatives (4a, b and 5a, b), but also dibenzodithiocins of new (dibenzodithiocins 2a, b) and known (dibenzodithiocins 3a, b) types.The analogous reaction of the 4-methylaroylamide 8a furnished the 4H-1,3-benzothiazine 9a, the dibenzodithiocin derivative 10a and benzonitrile.In contrast, 8b (the chloro analogue of 8a) furnished only benzonitrile and bis(4-chlorophenylmercapto)methane (11).The structures of the new compounds were confirmed by IR, 1H and 13C NMR, and (in part) by mass spectrometry.Temperature-dependent 1H NMR studies were used for the conformational analysis of 2a and its disulphone 6a; the nature and free enthalpies of activation of the two different conformational motions occuring at higher temperatures were determined.KEY WORDS - Dibenzodithiocins Synthesis 1H and 13C NMR Conformation Structural isomerism

Trithiatruxenes: A Family of Disc-like Mesogens with a New Polymorphism

A homologous series of hexa-n-alkanoyloxytrithiatruxenes (2,3,7,8,12,13-hexa-n-alkanoyloxybenzo-trisbenzothiophenes) (Cn HATXS) has been prepared with n = 9 to n = 13 in order to study the influence of the substitution of the tree methylenes of the truxene core by three sulphur atoms on the mesomorphic properties.Phase transitions were studied by hot stage microscopy and DSC.This series shows another example of an inverted sequence (crystal-ND nematic-D columnar-isotropic) and a new polymorphism with a columnar phase between Dh and Drd phases.

Monomethylthio analogues of 1-(2,4,5-trimethoxyphenyl)-2-aminopropane

Regiospecific syntheses of the three monomethylthio analogues of 1-(2,4,5- trimethoxyphenyl)-2-aminopropane are described. The three isomeric amines were evaluated for potential psychotomimetic potency using the rabbit hyperthermia assay. Enantiomeric com
