saturated nitrogen heterocycles-the synthetically more challenging variants of their aromatic relatives-can expedite the synthesis of biologically relevant molecules. Starting from a benzylic alcohol tethered to an unactivated alkene, an iron-catalyzed tandem alcohol substitution and hydroamination provides access to tetrahydroisoquinolines in a single synthetic step. Using a mild iron-based catalyst
饱和氮杂环的快速组装-芳香族近亲的合成更具挑战性-可以加快生物学相关分子的合成。从拴系到未活化烯烃的苯甲醇开始,铁催化的串联醇取代和加氢胺化可在单个合成步骤中获得四氢异喹啉。使用软铁基催化剂,这些操作的结合形成两个碳-氮键,并提供了独特的环化策略来访问该有价值的核。
