Versuchsvorschrift

BDAM (2.60 grams) was combined with ether (2 milliliters) and TMAL (1.0 milliliter) as described in Example 4, after which 1.50 grams of (+) dihydrocarvone were added. As in Example 4, a noticeable exotherm was observed. After 3 hours of stirring at room temperature, the reaction mixture was hydrolyzed as in Example 1. After the usual work up and column separation, 1.40 grams of 4-methyl-3-methylene-1-isopropenyl cyclohexane were isolated (95% yield).
