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.
本发明揭示了一种新的中间化合物,可高效地用于基于磺酰化学的类胡萝卜素化合物的合成,其制备方法以及使用上述新化合物的实际合成β-胡萝卜素的合成过程。β-胡萝卜素的合成的特点是C40化合物中含有苯磺酰基和X基团(卤素或醚)的双消除反应,可以通过新的C10二醛与两当量的C15烯丙基磺酰化合物的偶联反应制备,然后将得到的C40二醇的官能团转化为相应的卤化物或醚,以产生完全共轭的多烯链。
