  Enantioselective Syntheses of α-Fmoc-Pbf-[2-¹³C]-l-arginine and Fmoc-[1,3-¹³C₂]-l-proline and Incorporation into the Neurotensin Receptor 1 Ligand, NT₈₋₁₃

  摘要：

  Enantioselective syntheses of selectively labeled, orthogonally protected [2-C-13]L-arginine and [1,3-C-13(2)]-L-proline are described from the commercially available precursors [2-C-13]bromoacetic acid and potassium [C-13]cyanide, Interestingly the enhanced signal assigned to C-2 in the C-13 NMR spectrum of alpha-Fmoc-Pbf-[2-C-13]-L-arginine was very broad at room temperature. The two Fmoc-labeled amino acids were used to prepare [2-C-13]-Arg9 and [1,3-C-13(2)]-Pro 10 labeled ligand (NT8-13) by manual Fmoc-SPSS.
