1 serves as a model compound for natural products in which an OH‐group is attached to an asymmetric C‐atom . It was oxidized with PbO 2 to the paramagnetic phenoxy radical 2 . After addition of a chiral amine, two signals appeared in the ENDOR spectrum in the ratio 1:1 for the H‐atom at the asymmetric C‐atom. They are assigned to the two enantiomers ( R )‐ 2 and ( S )‐ 2 .
