title: Tandem azidination- and hydroazidination-Huisgen [3 + 2] cycloadditions of ynamides. Synthesis of chiral amide-substituted triazoles.
abstract: Tandem azidination- and hydroazidination-Huisgen [3 + 2] cycloadditions of ynamides are described here. These processes are regioselective and chemoselective, leading to the synthesis of chiral amide-substituted triazoles.
