A facile regioselective decomposition of tosylhydrazones using NaOH as a base in refluxing isopropyl alcohol is described. This finding has been successfully applied towards the synthesis of (±)-α-lipoic acid (1).

spectra have been used to assign the absolutestereochemistry of the chiral thioacetal sulphoxides. Optically pure samples of 2,2-dimethyl-1,3-dithiane 1-oxide, cis-2-methyl-1,3-dithiane 1-oxide, and trans-2-methyl-1,3-dithiane 1-oxide, have been obtained by a chemical resolution method which provides confirmation of optical yields and absolutestereochemistry.
