Carotenoids and related polyenes. Part 8.1 Total synthesis of optically active mytiloxanthin applying the stereoselective rearrangement of tetrasubstituted epoxideWe have employed the numbering system used in carotenoids

Biomimetic synthesis of mytiloxanthin 1 was accomplished with stereoselective rearrangement of the tetrasubstituted epoxide 5 as a key reaction. This is the first total synthesis of optically active all-E mytiloxanthin 1.
