API Intermediate Description: L-Proline, N-(methoxycarbonyl)-L-valyl-5-methyl-, (5S)- is a protected dipeptide derivative used as a synthetic intermediate in peptide and medicinal chemistry.It comprises an L-valine residue linked via an amide bond to 5-methyl-L-proline, with the N-terminus protected as a methoxycarbonyl (carbamate). The defined (5S) stereochemistry preserves the conformational preferences of the proline ring, which is critical for controlling backbone geometry in downstream synthesis.
