  The Synthesis of a Geminally Perfluoro-tert-butylated β-Amino Acid and its Protected Forms as a Potential Pharmacokinetic Modulator and Reporter for Peptide-Based Pharmaceuticals

  摘要：

  To modulate and report the pharmacokinetics of peptide-based pharmaceuticals, a novel geminally perfluoro-tert-butylated beta-amino acid (beta Fa) and its Fmoc- and Boc-protected forms were designed and synthesized. beta Fa was incorporated into a model tripeptide via standard solid-phase chemistry. Both the amino acid (free and protected) and the tripeptide show a sharp singlet F-19 NMR signal. Reversed-phase chromatography and 1-octanol/water partition measurements demonstrate that beta Fa is extremely hydrophobic.
