Epoxidation of tetramethyllimonene (1) gave monoepoxide 2t, which was opened regioselectively to endo and exo tetramethylated trans-carveols 3t and 5t, respectively.The alcohols were further oxidized to tetramethylcarvone (4) and its unstable exocyclic is
OXYGENATED LIMONENE ANALOGS. PREPARATION OF TETRAMETHYLATED CARVONE AND CARVEOLS VIA REGIOCONTROLLED OPENING OF TETRAMETHYLLIMONENE OXIDE.

Regioselective opening of trans epoxide 2 gave endo and exo tetramethylated trans carveols 3t and 4t, respectively, which were oxidized to tetramethylcarvone (5) and its unstable exocyclic isomer 6; reduction of 5 with DIBAH gave tetramethylated cis carve
