Proline and its derivatives are widely found in small-molecule drugs, peptidomimetics, and therapeutic peptides. Recent medicinal chemistry studies have shown that structures such as 4-fluoroproline, 4-(trifluoromethyl)proline, α-substituted proline, and bicyclic proline can alter molecular ...
Since the first proline-catalyzed asymmetric synthesis was reported in 1971, a number of asymmetric syntheses using proline and derivatives have been developed. Proline-type organocatalysts are predominantly applicable to a wide assortment of asymmetric aldol reactions and asymmetric ...
