  Conversion of carboxylic acids into acid azides using peptide coupling agents, EDC and HBTU is described. The procedure is efficient, practical and applicable to a diverse range of carboxylic acids including N-protected amino acids. Using the same reagents, one-pot synthesis of ureas, dipeptidyl urea esters and carbamates from acids has also been achieved.

  (9H‐fluoren‐9‐yl)methyl cation (C14H11+) from FmocNH = CHR+. In addition, characteristic immonium ions are also observed. The deprotonated ureidopeptide acids dissociate differently from the protonated ureidopeptides. The [M − H]− ions of ureidopeptide acids undergo a McLafferty‐type rearrangement followed by the loss of CO2 to form an abundant [M − H − Fmoc + H]− which is absent for protonated ureidopeptides

  [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.
