Process for the production of alpha-mercapto carbonic acid derivatives |
| abstract |
γ-mercaptocarboxylic acids and their derivatives, in particular esters and amides, are prepared from γ-butyrolactones via the corresponding thiolactones. The thiolactones are obtained by reacting the lactones with thiocarboxylates in polar solvents and converted into the γ-mercaptocarboxylic acid derivatives by ring opening with nucleophilic reagents such as, for example, alkali metal alcoholates. These are intermediates, for example for the synthesis of leukotriene antagonists. |
