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 formula (I): Ar-Ar' by photochemically reacting a precursor compound of formula (II): Ar-L-Ar' to form a biaryl compound of general formula: Ar-L-Ar' (II) → Ar-Ar' (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用途,特别是在制药和农药领域中的活性成分的制备中的用途。具体而言,它涉及一种通过光化学反应化学前体化合物(II):Ar-L-Ar'与形成一般式的联芳烃化合物(II)→Ar-Ar'(I)反应,从而实现联芳烃化合物(I)的区域控制制备的方法,其中Ar和Ar'分别表示未取代或取代的C6-C20芳基或由碳、氮、氧和硫选择的5-20个环原子的杂芳基,L表示如本文所定义的一个组-X-Y-Z-。这些联芳烃化合物通常适用于有机化学合成的广泛领域中的中间体或关键构建块,以及它们各自的用途。它们在活性成分合成领域中的用途是本发明的一个方面,它们在制备药用活性成分中的用途尤为理想。
