Synthesis and characterization of all-E-(4,4'-13C2)-astaxanthin strategies for labelling the C15-end groups of carotenoids

The all-E isomer of (4,4'-13C2)astaxanthin (1a) has been prepared by total synthesis starting from commercially available 99% 13C enriched acetonitrile. The labelled astaxanthin was obtained in high purity and with high isotope incorporation. For this synthesis, the C15 + C10 + C15 strategy was used. The central C10-synthon, 2,7-dimethylocta-2,4,6-triene- 1,8-dial (3), was coupled with 13C-enriched C15-phosphonium salt 2a. The new synthetic scheme for the preparation of the C15-phosphonium salt is discussed in this paper; the same scheme can be used to label all positions and combinations of positions of the C15-phosphonium salt.

Process for the manufacture of cyclohexene derivatives

The compound 6-hydroxy-3-(5-hydroxy-3-methyl-1,3-pentadienyl)-2,4,4-trimethyl-2-cyclohexen-1-one useful as intermediate for producing the natural coloring agent astaxanthin as well as a method for synthesizing astaxanthin from this compound and synthesizing the compound from 2-hydroxyketo isophorone.
