✦ Synopsis

Synthesis of Apocarotenoides with a Shifted Methyl Group; Structure Elucidation of Citrus‐Carotenoides

With regard to the investigation of the biosynthesis of the C~30~‐carotenoids in citrus fruits apocarotenoids with a methyl group shifted by one position (diapocarotenoids) were synthesized. Characteristical differences, especially in the 270‐MHz‐^1^H‐NMR. spectra between the apo‐ and the diapocarotenoids are reported. The comparison of the natural pigments with the synthetic compounds proves that the natural products belong to the apocarotenoids as has been postulated earlier.
