Efficient recycling of catalyst-solvent couples was showcased in enantioselective Lewis acid-catalyzed reactions that were run in highly Lewis basic environments in which there is a greater risk of metal leaching. The success is attributed to a bioinspired approach to heterogenize microhydrated chiral Lewis acids within appropriate hydrophobic cavities, thereby decreasing catalyst deactivation and
在对映选择性路易斯酸催化反应中展示了催化剂-溶剂对的有效回收,这些反应在高路易斯碱性环境中进行,其中金属浸出的风险更大。这一成功归功于一种仿生方法,可在适当的疏水腔内异质化微水合手性路易斯酸,从而减少催化剂失活并抑制金属浸出。
