• Ligand in the synthesis of cis-substituted cyclopropane carboxylic acids via C-H activation of cyclopropane carboxamides using Pd catalyst. • Linker in the preparation of multi-small molecule-conjugated PTX (paclitaxel) derivatives. It can be also used as a building block in the preparation of stapled α-helical peptides and peptide C-terminal thioesters 应用： Fmoc-Glu(OtBu)-OH（氧羰基-L-谷氨酸 5-叔-丁酯）可用于：配体，以使用Pd催化剂通过环丙烷酰胺C-H活化反应合成顺式取代环丙烷羧酸。多小分子共轭PTX（紫杉醇）衍生物制备中的连接剂。还可用作基本构成要素制备钉状α-螺旋肽和肽C-端硫代酸酯。 • Ligand in the synthesis of cis-substituted cyclopropane carboxylic acids via C-H activation of cyclopropane carboxamides using Pd catalyst. • Linker in the preparation of multi-small molecule-conjugated PTX (paclitaxel) derivatives.
