An efficient synthesis of fullerooxazoles was developed via PhI(OAc)2/I2-mediated [3+2] reaction of C60 with amides under photo-irradiation. The reaction was tolerant to various aryl and alkyl amides. The reaction mechanism was investigated in detail and a radical pathway was proposed for the formation of fullerooxazoles. Further transformation of compound 2l allowed the easy conjunction of fullerooxazole
在光照射下,通过PhI(OAc)2 / I 2介导的C 60与酰胺的[3 + 2]反应,开发了全氟恶唑的有效合成方法。该反应耐受各种芳基和烷基酰胺。详细研究了反应机理,并提出了形成全氟恶唑的自由基途径。化合物21的进一步转化使得富勒唑基部分易于与其他分子骨架结合。
