I found the field of Chemistry very interesting. Saw the article Preparation of Oxindoles via Visible-Light-Induced Amination/Cyclization of Arylacrylamides with Alkyl Amines published in 2020. Application In Synthesis of 1,4-Dioxa-8-azaspiro[4.5]decane, Reprint Addresses Yu, W; Liu, XY (corresponding author), Lanzhou Univ, Coll Chem & Chem Engn, 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
The cascade amination/cyclization ofN-arylacrylamides with alkyl amines under visible-light photoredox catalysis is realized via intermediacy of aminium radicals. The aminium radicals are generated by a two-step sequence which involves N-chlorination of alkyl amines and subsequent reductive N-Cl cleavage. This method provides a convenient access to aminated oxindoles.
