The invention relates to a process for preparing aryl- and heteroarylacetic acids and derivatives thereof by reaction of aryl or heteroaryl halides with malonic diesters in the presence of a palladium catalyst, of one or more bases and optionally of a phase transfer catalyst. This process enables the preparation of a multitude of functionalized aryl- and heteroarylacetic acids and derivatives thereof, especially also the preparation of arylacetic acids with sterically demanding substituents.
本发明涉及一种制备芳基和杂环基乙酸及其衍生物的方法,该方法通过在钯催化剂、一种或多种碱和可选相转移催化剂的存在下,将芳基或杂环基卤代物与丙二酸二酯反应而得。该方法使得可以制备多种官能化的芳基和杂环基乙酸及其衍生物,尤其是可以制备带有立体位阻取代基的芳基乙酸。
