Abstract

We present the results of the chemoselective reactivity of phenylcarbamates. Phenylcarbamates of primary amines are reactive to form urea, and phenylcarbamates of secondary amines can be used as tags due to the existence of rotamers. Moreover, deprotection attempts to to recover the primary amines in use of a catalytic amount of TBAF show the possibility of obtaining the symmetrical urea from the corresponding phenylcarbamate. We have begun the study of the transformation of Phoc carbamates into the corresponding free amines by TBAF. We present here our most significant results concerning the sensitivity of this reaction in terms of the solvent and substrate.
