A practical preparation of TM-α-terpineol (4), cis-TM-β-terpineol (6c), trans-TM-β-terpineol (6t), TM-Δ1,7,Δ8-menthadiene (7), its spirocyclic epoxide (5), and TM-isocryptone (8) is described (TM = tetramethyl).Some of the new tetram

Hindered Rotation of the Isopropenyl Group in Substituted Isopropenylcyclohexanes and Identification of Preferred Rotamers by Nuclear Magnetic Resonance. Bent Bonds May Better Bonds

The series of 2,2,6,6-tetramethyl-1-isopropenylcyclohexenes 2-6 shows hindered rotation of the isopropenyl group, the activation barrier ΔG(excit.) varying from 12.8 to >15.7 kcal/mol.Splitting patterns and chemical shifts of the olefinic protons of the i

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
