摘要:The invention concerns a temperature-stable labelling reagent of formula (I), wherein: R<1> represents H or an alkyl, aryl or substituted aryl group; R<2> represents a detectable marker or at least two detectable markers linked together by at least a multimeric structure; L is a linking arm comprising a linear catemer concatenation of at least two covalent bonds; and n is an integer equal to 0 or 1; R<3> and R<4> represent, independently of each other: H, NO2, Cl, Br, F, I, R<2>-(L)n-Y-X-, OR, SR, NR2, R, NHCOR, CONHR, COOR with R = alkyl or aryl, A is a linking arm comprising at least a double bond enabling the conjugation of the diazo function with the aromatic cycle; and u is a whole number between 0 and 2, preferably between 0 and 1; and -Y-X- represents -CONH-, -NHCO-, -CH2O-, -CH2S-. The invention also concerns a method for the synthesis of said markers and uses for labelling biological molecules, in particular nucleic acids, with a labelling reagent bearing the diazomethyl function. The invention is particularly applicable in the field of diagnosis.

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 subject of the present invention are the triazole derivatives, the synthesis and application thereof. These are new compounds obtained in reaction of 4-amino- 1,2,4- triazole with nitrobenzaldehyde derivatives. Compounds possess two chiral centres that play the crucial role in chemical and biological properties. New triazole derivatives are used as active substances in drugs preventing and/or curing infection caused by fungi or bacteria.
