N-[4-[(4S)-2,5-Dioxo-4-oxazolidinyl]butyl]-2,2,2-trifluoroacetamide; (S)-N-[4-(2,5-Dioxo-4-oxazolidinyl)butyl]-2,2,2-trifluoroacetamide; Lys(Tfa)-NCA;

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.
