Abstract: The one-pot synthesis of pentafluorophenyl-(tert-butoxycarbonylamino)methyl carbamates starting from N-Boc amino acids is described. Ultrasound mediated concomitant rearrangement and coupling reactions have resulted in the production of good yields of the active methyl carbamates. The carbamates have been employed as monomeric building blocks for the synthesis of dipeptidyl urea esters/acids. All the compounds obtained have been fully characterized by IR, ¹H NMR, ¹³C NMR and mass spectroscopy.
