process has been developed for the partial synthesis of (3R,3′R)-zeaxanthin and (3R,3′S; meso)-zeaxanthin from commercially available (3R,3′R,6′R)-lutein. This involves the regioselective hydroboration of a dehydration product of lutein, namely (3R)-3′,4′-didehydro-β,β-caroten-3-ol [(3R)-3′,4′-anhydrolutein], to yield a mixture of (3R,3′R)-zeaxanthin and (3R,3′S; meso)-zeaxanthin followed by separation
