Total synthesis of (3R,3′R,6′R)-lutein and its stereoisomers

(Chemical Equation Presented) (3R,3′R,6′R)-Lutein (1) is a major dietary carotenoid that is abundant in most fruits and vegetables commonly consumed in the U.S. and that accumulates in the human plasma, major organs, and ocular tissues. Numerous epidemiol

Confirmation of the absolute (3R,3′S,6′R)-configuration of (all-E)-3′-epilutein

Circular dichroism (CD) spectroscopy was used to distinguish between the isomeric (all-E)-configured 3′-epilutein (2) and 6′-epilutein (8) to establish the absolute configuration of epilutein samples of different (natural and semisynthetic) origin, including samples of 2 obtained from thermally processed sorrel. Thus, the CD data of lutein (1) and epilutein samples (2) were compared. Our results unambiguously confirmed the (3R,3′S,6′R)- configuration of all epilutein samples. Compound 2 was thoroughly characterized, and its 13C-NMR data are published herewith for the first time.
