First Total Synthesis of (+/-)-Peridinin, (+/-)-Pyrrhoxanthin and the Optically Active Peridinin

The first total synthesis of peridinin 1 and pyrrhoxanthin 2 has been accomplished via the reaction of the C15-epoxy formyl ester 21 with the C22-allenic sulfone 28 or the C22-acetylenic sulfone 39.A synthesis of the optically active peridinin has also be

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
