Procedure

Analogously to Example 1, from citraconic acid anhydride and 2-hydroxy-2-methylheptane-1-thiol in the presence of diisopropylamine and the usual working up of the reaction mixture, 3,6-dimethyl-2-oxo-6-pentyl-1,4-oxathiane-3-acetic acid is obtained. Using chromatographic purification it can be separated into two isomers:
