Photoredox-Induced Intramolecular 1,5-H Transfer Reaction of Aryl Iodides for the Synthesis of Spirocyclic γ-Lactams
摘要:
This work develops a photocatalysis method for the synthesis of gamma-spirolactams through a tandem intramolecular 1,5-HAT reaction-cyclization process. A variety of novel gamma-spirolactams are prepared in good to excellent yields with this method. This transformation features mild reaction conditions and exceptional functional group tolerance. Additionally, gamma-terpinene is applied to this transformation as a hydrogen atom donor for the first time.
