Umsetzungen von 3‐Nitro‐4‐Fluor‐Benzaldehyd mit Aminosäuren

Abstract: 3-Nitro-4-fluor-benzaldehyd wird hergestellt. Er setzt sich rnit Aminosauren leicht zu N-[2-Nitro-4-formyl-phenyl]-aminosauren um.Die Umsetzung des 1-Fluor-2.4-dinitro-benzols (Reaktion von Sanger) beruht auf dem EinfluD der Nitrogruppen auf die Reaktionsfkihigkeit des Fluors (mesomerer Effekt). Friiher wurde gezeigt, daD eine der Nitrogruppen durch eine Carboxyl-oder Carboxy-alkyl-Gruppel) oder durch eine Sulfogruppe2) ersetzt sein kann, und daO diese Fluorverbindungen sich analog rnit Aminosauren und Aminen … Show more

“…The synthesis of the vancomycin mimic started with the preparation of the two unnatural amino acids 7 and 17, a substituted phenylalanine derivative and a phenylglycine derivative, respectively. Fluoro(nitro)phenylalanine derivative 7 (Scheme ) was prepared from 4‐fluorobenzaldehyde ( 2 ) following known,35 but slightly modified procedures. Starting with a nitration reaction, and subsequent NaBH 4 reduction of the aldehyde group the resulting benzylic alcohol was converted into 4 with PBr 3 .…”
