Carotenoid Syntheses not involving any Wittig Olefination

Industrial Carotenoid Syntheses not involving any Wittig Olefination [Pg.261]

Carotenoids have so far only been synthesized industrially by Roche and BASF. As established vitamin A producers, both manufacturers have available a selection of precursors that are suitable for carotenoid syntheses, and they have experience in the construction of isoprenoid polyene chains. This is made clear when the Roche vitamin A process [10] is compared with the first industrial synthesis of (3,p-carotene (3) [1] developed some years later by the same group. [Pg.261]
