    摘要： An improved process for the preparation of polyenes by the Julia reaction comprises carrying out the allylation of the anion of an allyl aryl sulfone generated a strong base, and the elimination of arylsulfinic acid to form a double bond in the same inert polar solvent which is immiscible with water, preferably in a ketone of the formula IR.sup.1 --CO--R.sup.2 (I)where R.sup.1 and R.sup.2 are each straight-chain or branched alkyl of 2 to 4 carbons, or R.sup.1 and R.sup.2 together are tetramethylene or pentamethylene. The process is particularly important for the preparation of vitamin A derivatives. In the preparation of vitamin A aldehyde, for example, it is advantageous to use the same alkali metal alcoholate as strong base in both stages so that the conversion can be carried out as one-pot reaction.

    摘要翻译： 通过Julia反应制备多烯的改进方法包括进行产生强碱的烯丙基芳基砜的阴离子的烯丙基化，以及消除芳基亚磺酸在与不混溶的相同惰性极性溶剂中形成双键 其中R1和R2分别是2至4个碳的直链或支链烷基，或者R1和R2一起是四亚甲基或五亚甲基。 该方法对于制备维生素A衍生物尤为重要。 在维生素A醛的制备中，例如，在两个阶段中使用相同的碱金属醇盐作为强碱是有利的，因此转化可以作为一锅反应进行。
