摘要：

The creation of new ligand motifs is very important in the design of superior catalysts. Inspired by the great success of C2-symmetric ligands in asymmetric catalysis, 2 there is burgeoning interest in the invention of C3-symmetric chiral ligands and their applications in asymmetric catalysis. Considering that chiral oxazoline ligands are attractive as a consequence of their topography and ease of synthesis and modification, together with the wide application of bisoxazolines, the development and application of trisoxazolines have received more and more attention. The most notable C3-symmetric trisoxazolines 1, 6a
