Abstract: | A convenient 3-step synthesis of (R)-7-hydroxycarvone (2) has been developed starting from (S)-alpha-pinene (7), using photooxygenation, oxidation, and fragmentation reactions. An improved synthesis of epoxy alcohol 6 and an unusual Ti(OiPr)(4) catalyzed hydroxy epoxide to keto alcohol rearrangement are also described. |
