I found the field of Chemistry very interesting. Saw the article Iodine-promoted Intermolecular Dehydrogenation Diamination: Synthesis of Unsymmetrical ,-Diamido Ketones published in 2019. Application In Synthesis of 1,4-Dioxa-8-azaspiro[4.5]decane, Reprint Addresses Li, YJ (corresponding author), Zhejiang Univ Technol, Dept Chem & Chem Engn, State Key Lab Breeding Base Green Chem Synth Tech, Hangzhou 310032, Zhejiang, 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
Iodine-promoted direct diamination of ,-unsaturated ketone to form two C-N bonds has been developed starting from chalcone and secondary amine. This reaction was performed in THF at 50 degrees C in the presence of I-2 and K2CO3. The protocol is metal-free, operationally simple and carried out under mild conditions, providing an effective new way for directing diamination reactions.
Application In Synthesis of 1,4-Dioxa-8-azaspiro[4.5]decane. Welcome to talk about 177-11-7, If you have any questions, you can contact Zhang, YJ; Su, JY; Niu, WJ; Li, YJ or send Email.
