Article abstract of DOI:10.1002/hlca.19820650306

Starting from optically inactive astaxanthin intermediates, the highly oxygenated carotenoid astacene was synthesized in seven steps (55percent overall yield from 6-oxo-isophorone).Key features of the new approach are base- and acid-catalyzed rearrangements of acetylenic intermediates such as those described in Schemes 2, 7 and 8.
