Amphiphilic aminated fullerenes have a broad margin of safety and significant antitumor ***,we develop a simple and versatile synthesis strategy for tetraamino-[60]fullerene epoxide(C_(60)(NR^(1)R^(2))_(4)O)using C_(60)Cl_(6)as a precursor,which notably reduces the reaction time to less than 1 h while retaining a high yield of over 80%with both cyclic and linear secondary amine substrates even at the gram *** molecular structure of C_(60)(NR^(1)R^(2))_(4)O is first validated by single-crystal diffraction,and a two-step reaction mechanism comprising nucleophilic substitution of Cl and the oxidative elimination of Cl_(2)is proposed based on experimental verification and density functional theory simulation.A set of water-soluble aminated C_(60)(NR^(1)R^(2))_(4)O was prepared in large quantities,and in vitro antitumor evaluation unveiled the critical role that terminal primary amino moieties of C_(60)(NR^(1)R^(2))_(4)O play in their antineoplastic *** work provides an effective synthesis method for aminated C_(60)(NR^(1)R^(2))_(4)O,facilitating the development of fullerene-derived tumor-targeted drugs.
