The synthesis of two types of triazole-linked glycosyl amino acids, at C-4 and at
the anomeric position for mannopyranose and glucopyranose derivatives, respectively,
via a copper-catalyzed [3+2] cycloaddition of acetylenic amino acid derivatives and
azide-containing glycoside is described.
[3+2] cycloaddition - acetylenic amino acid - azidocarbohydrate - triazole - glycosyl
