Proline-Based Organocatalysts
Proline-based organocatalysts have attracted much attention in the field of organocatalysis in recent years, especially in metal-free catalytic reactions. Proline is a natural amino acid that not only has good catalytic performance, but also has a simple structure, is non-toxic, and has a wide range of sources, which conforms to the concept of green chemistry.
