The present invention relates to a method for the metal-free preparation of a biaryl compound by a photosplicing reaction and its use in the preparation of chemical compounds, preferably of active ingredients e.g. in the fields of pharmaceuticals and agrochemicals.
In particular, it refers to a method for the regiocontrolled preparation of a biaryl compound of general formula (I) by photochemically reacting a precursor compound of general formula (II) to form a biaryl compound of general formula (I)
wherein
Ar and Ar', independently of each other, represent an unsubstituted or substituted C6-C20 aryl group or a heteroaryl group with 5-20 ring atoms selected from carbon, nitrogen, oxygen and sulfur, and
L represents a group -X-Y-Z- as defined herein.
The biaryl compounds are generally suitable as intermediates or key building blocks in a very broad spectrum of organic chemical syntheses and their respective utilities. Their use within the field of synthesis of active ingredients is an aspect of the invention, and their use in the preparation of pharmaceutically active ingredients is particularly preferred.
本发明涉及一种通过光切割反应无金属制备联芳烃化合物的方法,以及其在化学化合物制备中的应用,特别是在制药和农药领域中的活性成分制备中的应用。具体而言,本发明涉及一种通过光化学反应预控制制备通式(I)的联芳烃化合物的方法,其中通过反应通式(II)的前体化合物形成通式(I)的联芳烃化合物,其中Ar和Ar'独立地表示未取代或取代的C6-C20芳基或5-20个环原子中选择的碳、氮、氧和硫的杂环基团,L表示定义如下的-X-Y-Z-基团。联芳烃化合物通常适用于广泛的有机化学合成的中间体或关键构建块及其相应的实用性。它们在活性成分合成领域的应用是本发明的一个方面,它们在制备药用活性成分方面的应用尤其受欢迎。
