42267-27-6 N-(4-(2,5-二氧代-4-恶唑烷基)丁基)-2,2,2-三氟乙酰胺

危险性质：非危险化学品

Used in the synthesis of new arborescent architectures of poly(L-lysine), called lysine dendrigraft (DGL) polymers. DGL polymers were prepd. through a multiple-generation scheme (up to generation 5) in a weakly acidic aq. medium by polycondensing N.vepsiln.-trifluoroacetyl-L-lysine-N-carboxyanhydride (Lys(Tfa)-NCA) onto the previous generation G(n-1) of DGL, which was used as a macroinitiator.

医药

合成路线：

• 步骤：在弱酸性水溶液介质中，将N-ε-三氟乙酰基-L-赖氨酸-N-羧酸酐(Lys(Tfa)-NCA)通过缩聚反应接枝到前一代G(n-1)的DGL上，以G(n-1)的DGL作为大分子引发剂，进行多代（最多至第5代）的合成；
• 条件：弱酸性水溶液介质；
• 代数：最多至第5代。
