  skos:definition "The Ugi reaction is a multi-component reaction in organic chemistry involving a ketone or aldehyde, an amine, an isocyanide and a carboxylic acid to form a bis-amide.The reaction is named after Ivar Karl Ugi, who first reported this reaction in 1959. The Ugi reaction is exothermic and usually complete within minutes of adding the isocyanide. High concentration (0.5M - 2.0M) of reactants give the highest yields. Polar, aprotic solvents, like DMF, work well. However, methanol and ethanol have also been used successfully. This uncatalyzed reaction has an inherent high atom economy as only a molecule of water is lost, and the chemical yield in general is high. Several reviews have been published. Due to the reaction products being potential protein mimetics there have been many attempts to development an enantioselective Ugi reaction, the first successful report of which was in 2018. (From DBpedia)"@en, "En chimie organique, la réaction de Ugi est une réaction à  plusieurs composants impliquant une cétone ou un aldéhyde, une amine, un isonitrile et un acide carboxylique pour former un bis-amide. La réaction est nommée en l'honneur d'Ivar Karl Ugi, qui est le premier à  l'avoir recensée en 1959. (Source : DBpedia)"@fr ;
