Starting from (R)-3-hydroxybutyric acid ((R)-10) the C45- and C50-carotenoids (all-E,25,2′S)-bacterioruberin (1), (all-E,2S,2′S)-monoanhydrobacterioruberin (2), (all-E,2S,2′S)-bisanhydrobacterioruberin (3), (all-E,2R,2′R)-3,4,3′,4′-tetrahydrobisanhydrobacterioruberin (5), and (all-E,S)-2-isopentenyl-3-4-dehydrorhodopin (6) were synthesized. By comparison of the chiroptical data of the natural and the synthetic compounds, the (2S)- and (2'S)-configuration of the natural products 1-3 and 6 was established.
