A mild and versatile method based on copper-catalyzed [3+2] cycloaddition (Meldal-Sharpless reaction) was developed to tether biomolecules, such as monosaccharides, biotin, cholesterol, or uridine to the N-atom of pyrrole. The required azido and alkyne functions can be placed in either reactant, i.e. in the pyrrole or the biomolecule. The products are interesting precursors for functionalized superparamagnetic polypyrrole core-shell nanoparticles.
一种温和且多功能的方法基于铜催化的[3+2]环加成反应(Meldal-Sharpless反应),用于将生物分子如单糖、生物素、胆固醇或尿苷与吡咯的氮原子连接。所需的叠氮和炔烃功能可以放置在任一反应物中,即在吡咯或生物分子中。所得到的产物是功能化超顺磁性聚吡咯核壳纳米粒子的有趣前体。
