Abstract
The synthesis of the low molecular weight sulfonic acids, 2-methyl-4-oxopentane-2-sulfonic acid, 1-hydroxyhexane-3-sulfonic acid, 1-oxohexane-3-sulfonic acid and 1-hydroxyhexane-1,3-disulfonic acid from trans-2-hexenal and ethyl hex-2-enoate is reported. These sulfonic acids are putative precursors to the important wine aroma thiols, 3-mercaptohexan-1-ol, 3-mercaptohexyl acetate and 4-mercapto-4-methylpentan-2-one
