A tandem ring-opening–cyclization reaction of cyclopropanes with imines in the presence of 5 mol% of scandium triflate was developed for the highly diastereoselective synthesis of multisubstituted pyrrolidines.

transaminations as a new type of dynamiccovalent reaction is described. The key 1,3‐proton shift is under complete catalytic control and can be conducted orthogonally to, or simultaneous with, transimination in the presence of an amine to rapidly yield two‐dimensional dynamicsystems with a high degree of complexity evolution. The transamination–transimination systems are proven to be fully reversible
