A Cu(OAc)-promoted heteroannulation of [60]fullerene with α-amino ketones has been exploited for the efficient synthesis of 2-fulleropyrrolines containing a trisubstituted or tetrasubstituted C═C bond via the formation of C-C and C-N bonds. Mechanistic study indicates that a radical process should be involved in this transformation. Furthermore, theoretical computations show that the process via the attack of the carbon radical generated from the employed α-amino ketone to [60]fullerene should be the preferred pathway. The electrochemical properties of the synthesized 2-fulleropyrrolines have also been investigated.
Cu(OAc)促进的[60]富勒烯与α-氨基酮的杂环化反应,通过形成 C-C 和 C-N 键,高效合成了含有三取代或四取代 C=C 键的 2-富勒吡咯啉。机理研究表明,该转化过程中应涉及自由基过程。此外,理论计算表明,通过所使用的α-氨基酮生成的碳自由基进攻[60]富勒烯的过程应该是首选途径。所合成的 2-富勒吡咯啉的电化学性质也进行了研究。
