    Abstract: The novel C dialdehyde compound which can be efficiently utilized in the synthesis of carotenoid compounds based on the sulfone chemistry, the preparation method of the same, and the expeditious and practical synthetic processes for lycopene and β-carotene by the use of the above novel compound are disclosed. The syntheses of lycopene and β-carotene are characterized by the processes of the coupling reaction between two equivalents of geranyl sulfone or cyclic geranyl sulfone and the above C dialdehyde, the functional group transformation reactions of the diol in the resulting C 40 coupling products to X's (either halogens or ethers), and the double elimination reactions of the functional groups of the benzenesulfonyl and X to produce the fully conjugated polyene chain of the carotenoids.
