(vinylthio)benzene (1) and then an electrophilic quenching followed by a further metalation/electrophilic quenching is a general method to prepare in one pot (alkylthio)benzenesortho, alpha-substituted with equal or different groups. The direct dimetalation of 1 affords the ortho, alpha-dilithiated species 15 besides other by-products. Starting from 15 it is possible to obtain in one step ortho, alpha-substituted
A pharmaceutical composition is provided that has a low toxicity, demonstrates superior physicochemical properties and pharmacokinetics, and has superior peripheral blood lymphocyte count lowering activity. The pharmaceutical composition contains a compound having general formula (I):
[Chemical Formula 1]
(wherein R
1
represents a methyl group or an ethyl group, R
2
represents a methyl group or an ethyl group, and R
3
represents a phenyl group substituted with 1 to 3 substituents selected from the group consisting of a halogen atom, a lower alkyl group, a cycloalkyl group, a lower alkoxy group, a halogeno lower alkyl group, a lower aliphatic acyl group and a cyano group), a pharmacologically acceptable salt thereof or a pharmacologically acceptable ester thereof.
Amidothiol derivatives have the formula
wherein:
R represents an alkyl, alk-2 to 6 - enyl, phenylalkyl, phenyl or heterocyclic group optionally substituted by one or more functional groups inert to electrochemical oxidation:
R1, R2, R3 and R4 independently represent hydrogen or substituent groups, and r5 represents alkyl, phenylalkyl or phenyl. The derivatives are useful in the preparation of pharmaceutically active compounds and dyestuffs and have herbicidal and/or antibacterial activity. The compounds can be prepared by electrochemical oxidation of a corresponding organic disulphide in the presence of the corresponding alkene and the corresponding organic nitrite, and treatment of the reaction product with water.
