Cucurbitaxanthin A (=(all-E,3S,5R,6R,3'R)-3,6-epoxy-5,6-dihydro-β,β- carotene-5,3'-diol; 1) was submitted to thermal isomerization and to I2- catalysed photoisomerization. The structure of the main reaction products (9Z)- (2), (9'Z)- (3), (13Z)- (4), and (13'Z)-cucurbitaxanthin A (5) was determined by their UV/VIS, CD, 1H-NMR, and mass spectra.
