The Cover Feature shows an abstract “bat”, one side is the cinchona alkaloid skeleton, and another side is the oxazoline dominant skeleton, which are combined to form a series of novel chiral ligands. The best ligand (structure shown in the left middle part of the picture and the corresponding steric configuration is shown in upper‐middle part of the picture) was applied to Pd(II)‐catalyzed aza‐Wacker oxidation tandem cyclization of aromatic nitrogen‐containing dienes. In addition, in the right middle of the feature is the steric configuration of the transition state, which is formed by the combination of metal ligand complexes and substrates.
