(5 R ,6 S ,5′ R ,6′ S )‐5,6,5′,6′‐Diepoxy‐β,β‐Carotene: Synthesis, Spectroscopical and Chiroptical Properties, and HPLC‐Behaviour Using the scheme C 13 + C 2 →C 15 + C 10 →C 40 , whereby C 13 = (5 R ,6 S )‐5,6‐epoxy‐β‐ionone [8], the title compound 11a , (R = H), has been prepared and characterized. It exhibits nearly identical CD spectra as violaxanthin ( 11b , R = OH).
