The methoxy-mercuration of (−)-menthyl crotonate, cinnamate, and β-methylcinnamate resulted in partial asymmetric syntheses of the corresponding β-methoxylated derivatives, (−)-R-β-methoxybutyric acid, (−)-S-β-methoxy-β-phenylpropyl alcohol, and (−)-S-β-methoxy-β-phenylbutyl alcohol. The results suggested an ionic mechanism involving a cyclic mercurinium ion as an intermediate, formed by the electrophilic
