I found the field of Chemistry very interesting. Saw the article Palladium-Catalyzed Amination/Dearomatization Reaction of Indoles and Benzofurans published in 2020. Application In Synthesis of 1,4-Dioxa-8-azaspiro[4.5]decane, Reprint Addresses Liang, YM (corresponding author), Lanzhou Univ, State Key Lab Appl Organ Chem, Lanzhou 730000, Peoples R China.. The CAS is 177-11-7. Through research, I have a further understanding and discovery of 1,4-Dioxa-8-azaspiro[4.5]decane
This report describes a palladium-catalyzed dearomatization and amination tandem reaction of 2,3-disubstituted indoles and benzofurans via the Catellani strategy. This reaction provides a new method for the construction of amino-substituted indoline-fused cyclic and benzofuran spiro compounds in good yields. The reaction has broad functional group compatibility and substrate scope.
Application In Synthesis of 1,4-Dioxa-8-azaspiro[4.5]decane. About 1,4-Dioxa-8-azaspiro[4.5]decane, If you have any questions, you can contact Zhang, Z; Zhang, BS; Li, KL; An, Y; Liu, C; Gou, XY; Liang, YM or concate me.
