标题:Use of functionalized onium salts as a soluble support for organic synthesis
发明人：VAULTIER MICHEL; GMOUH SAID; HASSINE FATIMA
权利人:CENTRE NAT RECH SCIENT; UNIV RENNES
摘要:The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula A₁⁺, X₁^-, wherein A₁⁺ represents a cation and X₁^- represents an anion.

摘要: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.
