A one-pot reaction for the synthesis of 1,4-disubstituted 1,2,3-triazoles from the alcohols via copper oxide nanoparticles (nano CuO) catalyzed nucleophilic substitution of alcohol with azide, followed by azide-alkyne 1,3-dipolar cycloaddition (click reaction) is reported. 1,4-Disubstituted 1,2,3-triazoles are obtained in good to excellent yields from a variety of readily available alcohols without the need for the preactivation and isolation of the azide intermediates.
报告了一种通过纳米氧化铜颗粒(nano CuO)催化叠氮化物亲核取代醇,然后进行叠氮-炔烃 1,3-二极环加成反应(点击反应),从醇中合成 1,4-二取代的 1,2,3-三唑的一锅反应。无需预活化和分离叠氮化物中间体,就能从多种现成的醇中以良好到极好的收率获得 1,4-二取代的 1,2,3-三唑。
