  The Synthesis of GV143253A: A Case Study for the Use of Analytical and Statistical Tools to Elucidate the Reaction Mechanism and to Optimize the Process

  摘要：

  GV143253A 1 is a broad-spectrum injectable beta-lactam belonging to the class of trinem antibiotics. This article describes the work which enabled a detailed process understanding via several analytical techniques and the subsequent optimization of a key intermediate. By means of a combined application of (31)P NMR spectroscopy and MS spectrometry, the main impurities have been identified and the reaction mechanisms clarified. Moreover, a design of experiments (DoE) approach was applied which substantially improved the overall yield.

  Novel aliphatic (19)F-substituted amino acid was designed as a (19)F NMR label for peptide studies. The synthesis was performed in 11 steps and 9% overall yield from a commercially available starting material. The key transformation was a decarboxylative fluorination of an aliphatic carboxylic acid with XeF2 in C6F6.
