3, and n is an integer from O to 6. It has been found that the enantiomers of the invention are able to release (R)- alpha-lipoic acid, ensuring a longer permanence in the body for the pharmacologically active principle than that obtainable by its direct administration, or to simulate the pharmacological action of alpha-lipoic acid itself, while exhibiting a much more intense and lasting activity.
