Total synthesis of acetylenic carotenoids. 3. First total synthesis of optically active 9-Z-(3R,3'R)-diatoxanthin and 9-Z-(3R)-7,8-didehydrocryptoxanthin.

Optically active 9-Z-(3R,3'R)-diatoxanthin and 9-Z-(3R)-7,8-didehydrocryptoxanthin were synthesised in an overall yield of 9percent and 11percent respectively, with a seven step C9+C6+C25=C40 strategy.A key intermediate was the previously undescribed C15-

Carotenoids and Related Compounds. Part 38. Synthesis of (3RS,3'RS)-Alloxanthin and Other Acetylenes

The all-trans, 9-cis, and 9,9'-di-cis forms of (3RS,3'RS)-alloxanthin have been synthesized, also the 9-cis-isomer of (3RS,6'RS)-crocoxanthin.Perhydrogenation of alloxanthin gives a product with the same optical properties as perhydrozeaxanthin.These resu
