optimization. However, most syntheses of triazole drugs involve isolation of highly explosive azides. Herein we report safe and high efficient syntheses of triazole drugs in aqueous/organic solvent systems with Cu2O nanoparticle (Cu2O-NP) as the catalyst of azide–alkyne cycloaddition (CuAAC). Since Cu2O-NP can be efficiently dispensed in aqueous and some organic solvents, the azide solutions from the previous
三唑部分经常用于药物发现和优化中。但是,大多数三唑类药物的合成都涉及高爆炸性叠氮化物的分离。在本文中,我们报告了在水/有机溶剂系统中以Cu 2 O纳米颗粒(Cu 2 O-NP)作为叠氮化物-炔烃环加成(CuAAC)催化剂的安全高效合成三唑药物的方法。由于可以将Cu 2 O-NP有效地分配在水性溶剂和某些有机溶剂中,因此先前制备的叠氮化物溶液无需分离即可直接用于下一CuAAC阶段。因此,该合成策略对于合成三唑药物是安全,方便和高产率的。
