Pyrrolidines and pyrrolidinones are highly important structural motifs in organic chemistry. They are present in many ligands for asymmetric catalysis, as catalysts in the ever-growing field of organocatalysis,[1] and in a vast number of natural products.[2] Moreover, pyrrolidines and nitrogen heterocycles, in general, are exceedingly important motifs in medicinal chemistry. The pursuit of new and efficient methods for the synthesis of ...
