A Concise Route to Cyclic Amines from Nitroarenes and Ketoacids under Iron‐Catalyzed Hydrosilylation Conditions

Starting from nitroarenes, under hydrosilylation conditions, using a well-defined N-heterocyclic carbene iron(0) catalyst, (IMes)Fe(CO)4, the corresponding aniline derivatives were produced in 61–92% isolated yields. More impressively, selective synthesis of cyclic amines such as pyrrolidines, piperidines and azepanes conducted levulinic acid, 1,5- 1,6-keto acids, respectively. The sequential procedure proceeded both visible light irradiation thermal conditions with 20 examples yields up to 69%.
