  Sulfone Coupling and Double-Elimination Strategy for Carotenoid Synthesis

  摘要：

  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.

  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.

  揭示了一种新型中间化合物，可在基于磺酮化学的合成中高效利用，以及该化合物的制备方法和利用上述新型化合物制备β-胡萝卜素的实际合成过程。β-胡萝卜素的合成特点是通过含有苯磺酰基和X基团（卤素或醚）的C40化合物的双消除反应来实现，该C40化合物可通过新型C10二醛与两当量的C15烯基磺酮的偶联反应制备，随后通过将得到的C40二醇的官能团转化为相应的卤化物或醚，从而产生完全共轭的聚烯烃链。
