Reactions of Amino Acids and Peptides, I. - The reaction of N-Methylvaline and N-Methylisoleucine with Trifluoroacetic AnhydrideN-Methylvaline, N-methylisoleucine and their alkyl esters react with trifluoroacetic anhydride to form stable, highly volatile 4-alkylidene-3-methyl-2-trifluoro-1,3-oxazolidin-5-ones in high yields. The structures of these compounds were established by proton magnetic resonance, mass spectrometry, und gas chromatography.
Notes:
Die Reaktion von N-Methylvalin, N-Methylisoleucin und deren Alkylester mit Trifluoracetanhydrid führt unter milden Bedingungen in guten Ausbeuten zu 4-Alkyliden-3-methyl-2-trifluormethyl-1,3-oxazolidin-5-onen. Die Struktur dieser leicht flüchtigen, stabilen Verbindungen wurde mittels protonmagnetischer Resonanz, Massenspektrometrie und Gaschromatographie bestimmt.
