An efficient conversion of the carboxylic group of N-Fmoc α-amino acids/peptide acids into N-formamides employing isocyanates as key intermediates
(Chemical Equation Presented) Reaction of 96% formic acid with isocyanates derived from N-Fmoc α-amino acids/peptide acids catalyzed by DMAP has yielded a new class of stable formamides as crystalline solids which have been characterized by IR, 1/su

Nα-Fmoc-peptide azides: Synthesis, isolation, characterization and utility in the extension of peptide chains
Syntheses of Nα-Fmoc-peptide azides employing acid chloride as well as mixed anhydride methods have been carried out. The resulting Fmoc-peptide azides prepared have been isolated as solids in good yield (75-92 %) and are found to be analytical
