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

Homologues of Monocyclic Monoterpenes. Tetramethylated Derivatives of Carvone, Carveol, β-Terpineol, Sobrerol, and Related Compounds

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
