Treatment of amines under a carbon dioxide atmosphere withtetramethylphenylguanidine (PhTMG) and diphenylphosphoryl azide (DPPA) in acetonitrile below 0 
C providescarbamoyl azides in high to excellent yields. In addition,epimerization is not observed when optically pure 
-aminoesters are used as substrates.
