The reactivity of 2,2,6,8-tetramethyltricyclo(6.2.2.01,6)dodecene (2) toward different metal salts has been explored. In the presence of Fe(II), Sn(II) and Ce(IV) ions, compound 2 underwent a rearrangement process to afford acyclic triketones Z-3 and E-3. The action of Zn powder in acetic acid resulted in an unexpected formation of furan 4 in high yield.
The invention features compositions for administration of an oxidatively transformed carotenoid, fractionated oxidatively transformed carotenoid and components of oxidatively transformed carotenoid. The compositions are useful for supplementing the diet of an animal.
