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.

Epoxidation of α-curcumene (III) followed by cleavage of the resulting 2,3-epoxy-2-methyl-6-(4'-methylphenyl)heptane (IV) with diisopropylamide affords the allylic carbinol (V).V on oxidation with Corey's reagent furnishes 2-methyl-6-(4'-methylphenyl)-1-h
