5‐iodouracil or 5‐iodouridine and a series of five‐membered heterocycles such as 1H‐pyrrole, furan, 2‐methylfuran, 1‐methyl‐1H‐pyrrole, thiophene, as well as benzene in MeCN/H2O with a Hg lamp, 5‐aryluracils and 5‐aryluridines were synthesized. The reaction proceeded smoothly without the requirement of adding any transition metals or ligands.
已发现以中等产率进行5-碘尿嘧啶和5-碘尿苷直接芳基化的方法。通过在MeCN /中辐照5-碘尿嘧啶或5-碘尿苷与一系列五元杂环的混合物,如1 H-吡咯,呋喃,2-甲基呋喃,1-甲基-1 H-吡咯,噻吩和苯用汞灯将H 2 O,5-芳基尿嘧啶和5-芳基尿嘧啶核苷合成。反应平稳进行,无需添加任何过渡金属或配体。
