1046-1053
An efficient synthesis of 2,4,5-trichlorophenyl-(9<i>H</i>-fluoren-9-ylmethoxycarbonylamino)methylcarbamates employing isocyanates derived from several Fmoc-amino acids has been described. All the carbamates made have been obtained as crystalline solids and are fully characterized by IR, <sup>1</sup>H NMR, <sup>13</sup>C NMR and mass spectrometry. They have been used as building blocks for the synthesis of several dipeptidyl urea esters. The coupling of carbamates with <i>N,O</i>-bis[trimethylsilyl]amino acids resulted in Fmoc-protected dipeptide urea acids in good yield as well as purity. All the dipeptidyl urea esters and acids made have been well characterized. |
