Pyrrolidines as Chiral Auxiliaries

2019
Despite the fact that various enantioselective catalytic reactions are available for many important stereoselective reactions, diastereoselective auxiliary-controlled synthesis is still an important area of organic synthesis. Chiral pyrrolidine auxiliaries are frequently used in this context, due to good availability and efficient transfer of chirality
