of heteroarenes using unprotected amino acids as stable alkyl radical precursors is reported. This one-pot procedure is performed open to air under aqueous conditions and is effective for several natural and unnatural amino acids. Heterocycles of varying structure are suitably functionalized, and reactivity trends reflect the nucleophilic character of the radical species generated.
据报道,使用未保护的氨基酸作为稳定的烷基自由基前体,可以有效,通用地进行杂芳烃的CH烷基化反应。这种一锅法在水性条件下露天进行,对几种天然和非天然氨基酸均有效。适当地官能化可变结构的杂环,并且反应性趋势反映了所产生的自由基物种的亲核特性。
