we report the development of biohybrid catalysts that are capable of catalyzing the aldol reaction. The use of biotinylated imidazolium salts in combination with racemic or enantiomerically pure catalytic anions allowed us to study the adaptive and cooperative positioning of the anionic catalyst inside the protein. Supramolecular encapsulation of the biotinylated catalyst into avidin resulted in good
在此,我们报道了能够催化醛醇缩合反应的生物杂化催化剂的发展。将生物素化的咪唑鎓盐与外消旋或对映体纯的催化阴离子结合使用,使我们能够研究蛋白质内部阴离子催化剂的自适应和协同定位。生物素化催化剂的超分子包封到抗生物素蛋白中,对在离子液体/水混合物中进行的醛醇缩合反应具有良好的选择性。
