A conjunctive diiodoheptaene for the synthesis of C2-symmetric carotenoids

(2E,4E,6E,8E,10E,12E,14E)-2,15-Diiodo-6,11-dimethylhexadeca-2,4,6,8,10,12, 14-heptaene, prepared by homometathesis, has been used in palladium-catalyzed Suzuki and Stille cross-coupling reactions with the appropriate partners to construct the C2-symmetric carotenoids β,β-carotene, lycopene, synechoxanthin and 4,4′-diapo-ψ,ψ-carotene-4,4′- dial.

Synechoxanthin, an aromatic C40 xanthophyll that is a major carotenoid in the cyanobacterium Synechococcus sp. PCC 7002

A major aromatic, dicarboxylate carotenoid (> 15% of total) was isolated from the euryhaline cyanobacterium Synechococcus sp. PCC 7002. This compound, which was given the common name synechoxanthin (1), has been assigned the structure (all-E) χ,χ-caroten-18,18′-dioic acid by a combination of spectroscopic (UV-vis, FT-IR, 1H and 13C NMR, LC-MS) and chemical methods. This discovery conclusively establishes that some cyanobacteria are capable of synthesizing aromatic carotenoids.
