I found the field of Chemistry very interesting. Saw the article Copper-Catalyzed ortho-Selective Dearomative C-N Coupling of Simple Phenols with O-Benzoylhydroxylamines published in 2019. COA of Formula: C7H13NO2, Reprint Addresses Wang, DH (corresponding author), Chinese Acad Sci, Shanghai Inst Organ Chem, CAS Key Lab Synthet & Self Assembly Chem Organ Fu, Univ Chinese Acad Sci,Ctr Excellence Mol Synth, 345 Lingling Rd, Shanghai 200032, Peoples R China.; Guo, YL (corresponding author), Chinese Acad Sci, Shanghai Inst Organ Chem, State Key Lab Organometall Chem, Univ Chinese Acad Sci,Ctr Excellence Mol Synth, 345 Lingling Rd, Shanghai 200032, 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
A Cu-catalyzed dearomative amination of simple phenols with O-benzoylhydroxylamines (R’RN-OBz) to synthesize alpha-aminocyclohexa-2,4-dienones is reported. This intermolecular transformation occurs exclusively at the position ortho to the hydroxyl group, providing a convenient method to synthesize the desired products in high yields. The reaction proceeds under mild conditions and tolerates a wide range of functional groups. Mechanistic studies indicate that this transformation proceeds via either (1) a single-electron transfer process involving attack of an N-centered radical onto the phenol or (2) a two-electron pathway involving addition of phenol to an electrophilic Cu-III-amino complex via an inner-sphere process.
