Safety of 4-Nitrobenzoic acid. I found the field of Chemistry very interesting. Saw the article Synthesis of Diastereoenriched alpha-Aminomethyl Enaminones via a Bronsted Acid-Catalyzed Asymmetric aza-Baylis-Hillman Reaction of Chiral N-Phosphonyl Imines published in 2020, Reprint Addresses Li, GG (corresponding author), Texas Tech Univ, Dept Chem & Biochem, Lubbock, TX 79409 USA.; Li, GG (corresponding author), Nanjing Univ, Sch Chem & Chem Engn, Inst Chem & BioMed Sci, Nanjing 210093, Peoples R China.; Jiang, B (corresponding author), Jiangsu Normal Univ, Sch Chem & Mat Sci, Xuzhou 221116, Jiangsu, Peoples R China.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid.
An effective chiral GAP methodology for preparing alpha-aminomethyl enaminones through a (R)-CSA-catalyzed asymmetric aza-Baylis-Hillman reaction is reported. Excellent yields and high diastereoselectivity could be obtained under mild conditions and convenient GAP techniques. The confirmations of the absolute configuration of N-phosphonyl imine and chiral enaminone by X-ray diffraction provides an explicit explanation of the chirality mechanism for GAP chemistry.
