Description
本发明涉及新化合物、它们的合成以及它们在有机合成中的用途,尤其是在维生素A或β-胡萝卜素或其衍生物(例如角黄素、虾青素或玉米黄质)的合成中的用途。特别要提到的是这种新化合物可在维生素A或β-胡萝卜素的合成、优选地维生素A的合成中用作中间体(结构单元)。
维生素A是用于许多应用的重要成分。维生素A在整个机体的多种功能中起作用,例如视觉过程、基因转录、免疫功能、骨代谢、血细胞生成、皮肤与细胞健康和抗氧化功能。
(全-E)-视黄醇(维生素A)
由于维生素A(以及其衍生物)的重要性和其合成的复杂性,一直需要有改善的生产方法。
本发明的目的是找到易于使用的化合物,其能够用于维生素A或β-胡萝卜素、优选地维生素A的改善合成中。通过下文所公开并描述的化合物和合成实现了此目的。
式(I)的化合物在现有技术中是未知的。本发明涉及式(I)的化合物,
其中R1表示C1-C15烷基片段或C2-C18烯基片段。
当R1是C1-C15烷基片段时,则优选地该烷基片段是线性的。尤其优选的烷基片段是甲基、乙基和十五碳烷基。
当R1是C2-C18烯基片段时,式(I)的化合物可以具有多于三个C-C双键。优选地,烯基片段是未支化的。
式(I)的化合物可以是任意立体异构形式。式(I)的化合物可以是全-E-构型的或全-Z-构型的,以及任何其他E/Z-构型的。

下面列出这些最优选的式(I)的化合物,如式(Ia)、(Ib)和(Ic):
此外,本发明还涉及用于生产式(I)的化合物的方法。
一种合适的用于生产式(I)的化合物的方法涉及如下方法,其中式(II)的化合物被还原成式(I)的化合物,
其中R1具有与式(I)中相同的含义。
令人惊奇的是,我们发现可以使用2-甲基-CBS-噁唑硼烷/硼烷二甲硫醚(2-甲基-CBS-噁唑硼烷=1-甲基-3,3-二苯基六氢吡咯并[1,2-c][1,3,2]噁唑硼烷(oxazaborole))来进行还原。可以使用2-甲基-CBS-噁唑硼烷的(S)构型或(R)构型以及外消旋体。2-甲基-CBS-噁唑硼烷通常与硼烷二甲硫醚组合使用。2-甲基-CBS-噁唑硼烷和硼烷二甲硫醚以相对于式(II)的化合物等摩尔量(或过量)的量使用。
通常,该反应在有机溶剂中进行。合适的溶剂为醚诸如THF、甲苯、甲基THF、甲基环戊基醚、叔丁基甲基醚、叔丁基乙基醚、叔戊基甲基醚或它们的混合物。
该反应在低温度下进行,优选地在-20℃至20℃、更优选地在-10℃至10℃的范围内的温度下。
去除溶剂。这优选地在减压下进行。然后使用公知的方法来纯化产物。式(II)的化合物在现有技术中是未知的。
因此,本发明的另一个实施方式涉及式(II)的化合物,
其中R1表示C1-C15烷基片段或C2-C18烯基片段。
当R1是C1-C15烷基片段时,则优选地该烷基片段是线性的。尤其优选的烷基片段是甲基、乙基和十五碳烷基。
当R1是C2-C18烯基片段时,式(II)的化合物可以具有多于三个C-C双键。优选地,烯基片段是未支化的。
式(II)的化合物可以是任意立体异构形式。式(II)的化合物可以是全-E-构型的或全-Z-构型的,以及任何其他E/Z-构型的。
式(II)的化合物可以是异构体纯的形式,但式(II)的化合物也可以是至少两种异构形式的混合物。这些最优选的式(II)的化合物是其中R1是甲基、乙基或十五碳烷基的那些。
通过式(III)的化合物与式(IV)的化合物的反应来生产式(II)的化合物。
通常式(III)的化合物与式(IV)的化合物的反应在极性非质子传递溶剂中进行。优选的溶剂是醚,例如THF、甲基THF、甲基环戊基醚、叔丁基甲基醚、叔丁基乙基醚、叔戊基甲基醚或它们的混合物。

钯催化剂可以选自以下的组:双(三芳基膦)二卤化钯(II)和螯合的双(二芳基膦烷烃)二卤化钯(II),其中烷烃是线性C2至C6烷基片段。铜催化剂可以是亚铜(I)盐、优选地亚铜(I)卤化物、更优选地碘化亚铜(I)。
可以根据现有技术中已知的方法来生产式(III)的化合物。GB1034189公开了生产式(III)的化合物的方法,因此其通过引用并入本文。
式(IV)的化合物在现有技术中是未知的。可以使用至少一种氯化反应物氯化式(V)的化合物来生产式(IV)的化合物,
其中R1表示C1-C15烷基片段或C2-C18烯基片段。
当R1是C1-C15烷基片段时,优选地该烷基片段是线性的。尤其优选的烷基片段是甲基、乙基和十五碳烷基。
当R1是C2-C18烯基片段时,式(V)的化合物可以具有多于三个C-C双键。优选地,烯基片段是未支化的。
氯化反应物是公知的且广泛使用的。对于式(V)的化合物的氯化来说,可以使用任意氯化试剂(或其混合物)。氯化试剂的实例为草酰氯、五氯化磷、亚硫酰氯、氧氯化磷、氯气、氯酸、五氯化锑(V)、次氯酸、N-氯代丁二酰亚胺、三氯化磷、磺酰氯、四氯化碳、氰尿酰氯。优选的氯化试剂是草酰氯、五氯化磷、亚硫酰氯和氧氯化磷。通常以相对于式(V)的化合物的量稍微摩尔过量添加氯化试剂。
