title: (1R,4R,7S)-1,7-Dimethyl-7-(phenyl-sulfonyl-meth-yl)spiro-[bicyclo-[2.2.1]heptane-2,2'-1,3-dioxolane].
abstract: In the title compound, C(18)H(24)O(4)S, the chiral bicyclo-[2.2.1]heptane group is not symmetrical due to the influence of the substituents. The angle between the three-atom bridge plane and the four-atom planes of the boat-shaped six-membered ring are 55.07 (19) and 56.24 (19)°. The bridgehead angle is 92.75 (17)°.
