Calcium iodide (CaI2) catalyzes cycloaddition reaction in Nenitzescu synthesis to afford 5-hydroxyindoles from corresponding quinones and enamines. This method introduces CaI2 as a catalyst in performing this type of condensation reaction for the first time and presents advantages in using nontoxic metal, work-up simplicity, functional group tolerance, and can compete with other methods to overcome
碘化钙 (CaI 2 ) 催化 Nenitzescu 合成中的环加成反应,从相应的醌和烯胺中得到 5-羟基吲哚。该方法首次引入CaI 2 作为催化剂进行此类缩合反应,具有使用金属无毒、后处理简单、官能团耐受性强等优点,可与其他方法一争高下,克服目前存在的诸如低产率和聚合副反应。 图形概要
