Carotenoids and related polyenes. Part 3. First total synthesis of fucoxanthin and halocynthiaxanthin using oxo-metallic catalyst

The first total synthesis of optically active fucoxanthin 1 and halocynthiaxanthin 2 had been accomplished via the 8-oxo compound 5, efficiently prepared by rearrangement of the α-acetylenic alcohol 10 using oxo-metallic catalyst and subsequent iodine-catalysed double-bond shift.

Total synthesis of photosynthetic pigment fucoxanthin by use of oxo- metallic catalyst

The first total synthesis of optically active fucoxanthin 1 has been accomplished via the 8-oxo-compound 7, efficiently prepared by rearrangement of the α-acetylenic alcohol 2 using oxo-metallic catalyst and subsequent iodine catalyzed double bond-shift.
