NH-1,2,3-triazoles from azidomethyl pivalate and carbamates: Base-labile N-protecting groups

Abstract

NH-1,2,3-triazoles have been prepared via the copper(I)-catalyzed 1,3-dipolar cycloaddition between terminal alkynes and three N-protected organic azides, azidomethyl pivalate, azidomethyl morpholine-4-carboxylate, and azidomethyl N,N-diethylcarbarnate. These organic azides were easily prepared on 0.1-mol scale in one or two steps from inexpensive commercially available materials. The cleaving properties of N-substituents in the resulting 1,2,3-triazole products with aqueous sodium hydroxide vary from
