We optimized synthesis of several new amino acid and peptide MPA derivatives by conjugation with various condensation reagents. Amino acid MPA derivatives 11e17 were obtained by means of a condensation reagent 1-ethyl-3-(3 0 -dimethylaminopropyl)carbodiimide (EDCI) in the presence of 4-(dimethylamino)pyridine (DMAP) acting as a base in anhydrous N,Ndimethylformamide (DMF) (Scheme 1). In case of derivatives of MPA with isoleucine 14 or malonate 17 moiety the best results were received using the T3P/Et 3 N procedure, where triethylamine acts as a base and propanephosphonic acid anhydride (T3P) is a condensing reagent (Scheme 2). Synthesis of amino acid derivatives of MPA 11e17 using the EDCI/DMAP method. ./cache/cord-262643-wydc0wyd.txt ./txt/cord-262643-wydc0wyd.txt
