Li, G.; Yu, W.; Cui, Y. A Homochiral Nanotubular Crystalline Framework of Metallomacrocycles for Enantioselective Recognition and Separation. J. Am. Chem. Soc. 2008, 130, 4582−4583. This work highlights the critical importance of chiral microenvironments within a self-assembled homochiral metallacycle that is capable of exceptionally high enantioseparation properties.
Dong, J.; Tan, C.; Zhang, K.; Liu, Y.; Low, P. J.; Jiang, J.; Cui, Y. Chiral NH-Controlled Supramolecular Metallacycles. J. Am. Chem. Soc. 2017, 139, 1554−1564. This work clearly demonstrates that the deployment of chiral NH groups within a metallacyclic system can significantly enhance host−guest enantioselective recognition.
Jiao, J.; Tan, C.; Li, Z.; Liu, Y.; Han, X.; Cui, Y. Design and Assembly of Chiral Coordination Cages for Asymmetric Sequential Reactions. J. Am. Chem. Soc.2018, 140, 2251−2259. This work describes highly stable chiral metallacages bearing catalytically heterometallic active sites that enable sequential asymmetric reactions with up to 99% ee, highlighting the intermetallic synergy effect of supramolecular catalysts.
