A new approach to not-readily-available optically active tertiary propargylic alcohols through palladium/H⁺-cocatalyzed carboxylation of racemic tertiary propargylic alcohols with CO and MeOH has been described. Both enantiomers can be obtained with no less than 90% ee utilizing (R) or (S)-DTBM-Segphos. Various transformations of the optically active alcohols have been demonstrated.
