Cas no 97373-38-1 (D-Proline, 5-methyl-,methyl ester, (5R)-rel-)

The compound D-Proline, 5-methyl-, methyl ester, (5R)-rel- is a chiral proline derivative with a methyl substituent at the 5-position and a methyl ester functional group. Its stereochemical configuration, particularly the (5R)-relative form, makes it valuable in asymmetric synthesis and peptide chemistry, where rigid secondary structures are required. The methyl ester enhances solubility and reactivity, facilitating its use in coupling reactions. This derivative is particularly useful in the preparation of modified peptides and as a building block for pharmaceuticals or catalysts. Its structural features contribute to improved stability and controlled stereoselectivity in synthetic applications.
