  An Efficient Conversion of the Carboxylic Group of N-Fmoc α-Amino Acids/Peptide Acids into N-Formamides Employing Isocyanates as Key Intermediates

  摘要：

  [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.

  The synthesis of hydroxamic acids starting from carboxylic acids employing 1-propanephosphonic acid cyclic anhydride (T3P) activation is described. Application of ultrasonication accelerates this conversion. Further, the T3P has also been employed to activate the hydroxamates, leading to isocyanates via the Lossen rearrangement. The isocyanates were trapped with suitable nucleophiles to afford the

  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.
