various aldehydes followed by a Cu-catalyzed azide-alkyne 1,3-dipolar cycloaddition (CuAAC) is reported. 1,4-Disubstituted 1,2,3-triazoles are obtained in good to excellent yields from a variety of readily available aldehydes without the need for isolation of the alkyne intermediates. The reaction has a broad scope, allows the formation of new bioconjugates and is applied for the synthesis of new boronic
报道了一种可靠且操作简单的一锅反应,用于各种醛的单碳同系化,然后是铜催化的叠氮化物-炔烃 1,3-偶极环加成 (CuAAC)。1,4-二取代的 1,2,3-三唑可以从各种容易获得的醛中以良好到极好的收率获得,而无需分离炔中间体。该反应具有广泛的范围,允许形成新的生物共轭物,并用于合成新的基于硼酸的荧光传感器。
