Abstract

Synthesis of new types of peptidomimetics and glycosylated amino acids possessing 1,2,3-triazole and carbamate moieties is described. Poc-protected amino acid esters/1-amino sugars were subjected to Cu(I) catalyzed [2+3]cycloaddition with desired azides under click protocol to obtain novel peptide and carbohydrate mimetics. The reaction is rapid, efficient and all the products are isolated in good yield and excellent purity.
