I found the field of Chemistry very interesting. Saw the article Direct N- sec -Alkylation of Amides by Reaction of -Halohydroxamates and Sulfonylindoles: An Approach to 3-Indolyl Methanamines published in 2019.0. Category: pyridine-derivatives, Reprint Addresses Kang, TR (corresponding author), Chengdu Univ, Coll Pharm & Biol Engn, Chengdu 610106, Sichuan, Peoples R China.; Kang, TR (corresponding author), China West Normal Univ, Coll Chem & Chem Engn, Nanchong City 637002, Peoples R China.. The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde
A catalyst-free, base-mediated N- sec -alkylation of amides by reaction of sulfonylindoles and -halohydroxamates has been developed. The N- sec -alkylation of amides reaction is based on an intermolecular nucleophilic addition of vinylogous imine with N -(benzyloxy)meth-acrylamide/azaoxyallyl cations formed in situ and represents a simple way to give polyfunctionalized 3-indolyl methanamines in good to excellent yields.
