1-Acetyl-4-methyl-3-cyclohexen-1-ol, a useful precursor in the synthesis of cyclic monoterpenes

A synthesis of monocyclic monoterpenes: p-mentha-1,8-dien-4-ol (1), terpinolene (4) and p,α-dimethylstyrene (5) from the titled compound 7, as a common precursor, is reported.

73. Synthesis of (+)-(4S,8R)-8-Epi- and (-)-(4R,8S)-4-Epi-β-bisabolol

The first total enantioselective synthesis of (+)-(4S,8R)-8-epi-β-bisabolol ((+)-1) and of (-)-(4R,8S)-4-epi-β-bisabolol ((-)-1) is reported.The key step in the synthesis is the kinetic resolution of (+-)-5 by means of the Sharpless epoxidation yielding (

Terpenes and Terpene Derivatives, XIX. - On the Selective Epoxidation of rac-β-Curcumene. Synthesis of 1-(4-Methyl-1,4-cyclopentadien-1-yl)ethanone

Epoxidation of rac-β-curcumene (1) yields a mixture containing the monoepoxides 2-4, and 6 in a ratio of 4:1:5:1 besides some other products.- Birch reduction of 17 gives only the hydrocarbon 18, even via the alkoxide. - The uncatalyzed Diels-Alder reaction of isoprene (10) with 3-butyn-2-one (11) leads to a mixture of the ketones 12-15 with a large amount of the 1,5-isomer 13 and the acetophenones 14 and 15.By TiCl4 catalysis the regioselectivity 12/13 can be enhanced to 94:6.
