Synthesis and Performance of l-Tryptophanamide and (S)-1-(Naphthalen-2'-yl)ethanamine-Based Marfey-Type Derivatives for Amino Acid Configurational Analysis: Diastereomeric Resolutions Directed by π-Cation Bonding
{{output}}
The configurational analysis of amino acids (AAs) in natural product peptides, often containing nonproteinogenic AAs, is mostly carried out by the venerable Marfey's method using a chiral derivatizing agent (CDA) 1-fluoro-2,4-dinitrophenyl-5-l-alaninamide (l-... ...
