Abstract

Process for the preparation of new derivatives of the alpha-mercapto-carboxylic acid of the general formula I ** (See formula) ** in which R1 means hydrogen, an aliphatic, cycloaliphatic, aromatic or araliphatic radical, R2 means hydrogen or a lower alkyl radical, and R3 means a lower alkyl radical, hydrogen, a monovalent cation or the normal equivalent of a polyvalent cation, characterized in that an ester capable of reacting a hydroxyl compound of the general formula II ** (See formula) ** in which R3 'means a lower alkyl radical, and R1 and R2 have the significance indicated above, it is reacted with a 1-adamantantiol salt capable of reacting, and if desired, the alkyl ester of alpha- (adamant-1-ylthio) -carboxylic acid originated to reach the free acid or a salt, and if desired the free acid or the salt is transformed into another salt with an inorganic or organic base, or if desired, the racemic acid is split into its antipodes.
