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.
揭示了一种可以在基于磺酮化学的类胡萝卜素化合物合成中高效利用的C二醛化合物,以及该化合物的制备方法,以及通过使用上述新颖化合物快速实用地合成番茄红素和β-胡萝卜素的合成过程。番茄红素和β-胡萝卜素的合成特点在于通过两等量的戊二烯基磺酮或环戊二烯基磺酮与上述C二醛之间的偶联反应过程,将结果产生的C40偶联产物中的二醇的官能团转化反应为X(可能是卤素或醚),以及苯甲磺酰基和X的官能团的双消除反应,以产生类胡萝卜素的完全共轭聚烯链。
