  Synthesis of Peptidyl Ureas Using p‐Nitrophenyl‐(9‐fluorenylmethoxy Carbonylamino)methyl Carbamate Derivatives

  摘要：

  An efficient synthesis of p-nitrophenyl-(9-fluorenylmethoxy, carbonylamino) methyl carbamates using isocyanates derived from Fmoc-amino acid azides and p-nitrophenol in presence of an equimolar quantity of N-ethyldiisopropyl amine is described. All the carbamates have been isolated as crystalline solids and are fully characterized. Further, their utility for the synthesis of dipeptidyl ureas has been demonstrated.

  [Graphics]Reaction of 96% formic acid with isocyanates derived from N-Fmoc alpha-amino acids/peptide acids catalyzed by DMAP has yielded a new class of stable formamides as crystalline solids which have been characterized by IR, H-1 NMR, C-13 NMR, and mass spectroscopy. Conversion of the side chain carboxylic acid of N-Fmoc-5-oxazolidinones of Asp/Glu into the N-formyl group also has been accomplished. The reaction is simple, mild, and high yielding.
