Terpenes and Terpenoid Cmpounds, 15. - Preparation of Tetramethylated Perillyl Alcohol and Related

Lithium perchlorate-induced rearrangement of 1,3,3,5,5-pentamethyl-4-(1-methylethenyl)-7-oxabicycloheptane (2) in toluene furnishes the epimeric tetramethylated dihydrocarvones 4t, c and 2,2,4,4-tetramethyl-6-methylene-3-(1-methylethenyl)-trans-cyc

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

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
