Total synthesis of C31-methyl ketone apocarotenoids. Part 4. First total synthesis of (3S,5R,6R)-paracentrone

Optically active (all-E)-(3S,5R,6R)-paracentrone has been prepared by total synthesis for the first time, in 3% overall yield over 13 linear steps from the readily available (4R,6R)-actinol, (2E)-3-methylpent-2-en-4-yn-1-ol, (all-E)-2,7-dimethylocta-2,4,6

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

CAROTENOID METABOLISM AND THE BIOSYNTHESIS OF ABSCISIC ACID

The conversion of all-trans-violaxanthin to 9'-cis-neoxanthin was shown to occur in fluridone-treated etiolated Lycopersicon and Phaseolus seedlings, following exposure to light.The results of deuterium oxide labelling experiments supported this precursor/product relationship, and provided further evidence for the origin of abscisic acid.Several apo-carotenoids, putative by-products of abscisic acid biosynthesis, were synthesised by chemical oxidation but were not detected in plant extracts.In vitro, lipoxygenase cleaved neoxanthin and violaxanthin down to small (/=C13) fragments.It may be that in vivo any apo-carotenoids formed by the specific cleavage of 9'-cis-neoxanthin, during abscisic acid biosynthesis, are rapidly metabolized by lipoxygenase or similar enzymes.
