syn-Dispiro­[1,3-dioxolane-2,17′-penta­cyclo­[12.2.1.16,9.02,13.05,10]octa­decane-18′,2′′-[1,3]dioxolane]-7′,15′-diene

The title compound, C(22)H(28)O(4), is composed of a central octa-decane ring and two spiro-[bicyclo-[2.2.1]hept[2]ene-7,2'-[1,3]dioxolane] units. This polycycle has pseudo twofold symmetry and the central cyclo-octane ring has a distorted boat configuration.

The title compound, C(22)H(20)Cl(8)O(4), was prepared as part of the synthesis of precursors for the preparation of fluorinated mol-ecular tweezers. The mol-ecule sits on an inversion center, thus requiring that the cyclo-octane ring adopt a chair conformation.

D-004, a lipid extract from royal palm (Roystonea regia) fruits, has shown to inhibit prostate 5-α-reductase in vitro, and to prevent prostate hyperplasia (PH) induced with T, not with DHT, in rodents, but its potential estrogenic or antiestrogenic effects had not been studied yet. This study investigated whether D-004 produces estrogenic or antiestrogenic effects, as assessed in the uterotroph...
