Two Optically Active Luteochromes: Preparation, Spectra and Chiroptical and Chromatographic Properties Selective rearrangement of (5 R ,6 S ,5′ R ,6′ S )‐5,6:5′, 6′ ‐diepoxy‐5,6,5′, 6′ ‐tetrahydro‐ β,β ‐carotene with the aid ofan ethereal solution of malonic acid leads to the mixture of the C(8′)‐epimeric luteochromes. HPLC separation gave the pure isomers. This is the first report on th preparation of optically active luteochromes.
