for the synthesis of aryl amides via oxidative copper-catalyzed coupling of commercially available aryl boronic acids and bench stable Nα-protected amino-acid azides is reported. The potential utility of this protocol is demonstrated through a survey of diversely substituted aryl boronic acids and several side-chain functionalized amino-acid azides, leading to the preparation of the desired amidated

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.
