    The present invention describes a novel synthetic method for preparing the key intermediate 2,6,10-trimethyl-1,1-dialkoxy-3,5,9-undecatriene of lycopene. An existing synthetic method have some disadvantages that it is very difficult to gain the raw material dialkyl 4-methyl-5,5-diakoxy-1-pentene-1-phosphonate (10) because no effective synthetic method can be adopted, and furthermore the obtained target compound is composed of several cis/trans isomers. This invention relates to a process comprising a condensation step wherein a starting C10-phosphonate is changed to its carbanion completely at a temperature of −40˜30 under an atmosphere of a non-reactive gas in an organic solvent catalyzed by base, and then C4-dialkyl is added to undergo Wittig-Horner condensation. This invention affords all trans C14-acetal and this method is characterized with the advantages of simple procedure, easy access to raw material and low cost, which makes it has the value of industrial application.
    本发明描述了一种新颖的合成方法,用于制备番茄红素的关键中间体2,6,10-三甲基-1,1-二烷氧基-3,5,9-十一烯。现有的合成方法存在一些缺点,即很难获得原料二烷氧基-4-甲基-5,5-二烷氧基-1-戊烯-1-膦酸酯(10),因为没有有效的合成方法可采用,而且所得目标化合物由几种顄/反异构体组成。本发明涉及一种包括缩合步骤的过程,在该过程中,起始的C10-膦酸酯在非反应性气体氛围下,在有机溶剂中由碱催化完全变为其碳负离子,然后加入C4-二烷基进行威蒂-霍纳缩合。本发明提供了全顄C14-缩醛,该方法具有简单的操作程序、易获得原料和低成本的优点,使其具有工业应用的价值。

    Zur Herstellung von 1,4-Butandial (Succindialdehyd) wird von Acrolein ausgegangen. Das Acrolein wird mit einem Alkanol zu einem 3,3-Dialkoxy-1-propen umgesetz und dieses wird in Gegenwart von Hydridotristriphenylphosphin-rhodiumcarbonyl sowie Triphenylphosphin oder Triphenylphosphit als Katalysator hydroformyliert. Das hierbei gebildete 4,4-Dialkoxybutanal wird durch Destillation aus dem Hydroformylierungsprodukt abgetrennt und zum 1,4-Butandial hydrolysiert.
