Carotenoids and related polyenes. Part 5. Lewis acid-promoted stereoselective rearrangement of 5,6-epoxy carotenoid model compounds

The novel acyclic tetrasubstituted olefinic end group and the cyclopentyl end group of carotenoids were obtained by Lewis acid-promoted stereoselective rearrangement of the epoxide end group of 5,6-epoxy carotenoids. The scope and limitation of this rearr
