X-ray investigations of bicyclic alpha-methylene-delta-valerolactones. V. (4aS,7R,8aR)-7-isopropenyl-4a-methyl-3-methyleneperhydrochromen-2-one.
The title compound, C(14)H(20)O(2), adopts a conformation in which the delta-valerolactone and cyclohexane rings are almost coplanar with one another. The gamma-methyl substituent occupies an axial position with respect to the cyclohexane ring. The delta-valerolactone moiety adopts an envelope arrangement, while the cyclohexane ring exists in a chair conformation.
