The novel intermediate 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 practical synthetic process for preparing β-carotene by the use of the above novel compound are disclosed. The synthesis of β-carotene is characterized by the double elimination reactions of the C40 compound containing both the benzenesulfonyl group and the group X (either halogen or ether), which can be prepared by the coupling reaction of the novel C10 dialdehyde with two equivalents of the C15 allylic sulfone, followed by the functional group transformation of the resulting C40 diol either to the corresponding halide or to the ether, to produce the fully conjugated polyene chain.

A highly efficient synthetic method of carotenoid compounds has been developed on the basis of the sulfone coupling and double-elimination strategy. This method highlighted the sulfone-mediated coupling with the novel C 10 dialdehyde, 2,7-dimethyl-4-octenedial, which was easily prepared and efficiently utilized in the synthesis of the conjugated polyene chains.
