3′-Epilutein (=(all-E,3R,3′S,6′R)-4′,5′- didehydro-5′,6′-dihydro-β,β-carotene-3,3′-diol; 1), isolated from the flowers of Caltha palustris, was submitted to both thermal isomerization and I2-catalyzed photoisomerization. The structures of the main products; (9Z)-1, (9′Z)-1, (13Z)-1, (13′Z)-1, (15Z)-1, and (9Z,9′Z)-1 were determined based on UV/VIS, CD, 1H-NMR, and MS data.
