Abstract

A method of C-H functionalization of the N-protected alkyl 1,2,3-triazole-4-carboxylates with various C-, P- and S-electrophiles using an in situ generated turbo-Hauser base, has been developed. The resulting compounds underwent N- and O-deprotection giving rise to the corresponding NH-5-substituted 1,2,3-triazole-4-carboxylates, which possess multiple sites for further functionalization.
