I found the field of Chemistry very interesting. Saw the article Highly Enantioselective Synthesis of Acyclic N,N ‘-Acetals by Chiral Urea Derived from Quinine Catalyzed the Addition of Aryl Amines to Isatin-Derived Ketimines published in 2019.0. Quality Control of Diphenylmethanamine, Reprint Addresses Lin, YJ; Duan, HF (corresponding author), Jilin Univ, Dept Organ Chem, Coll Chem, 2699 Qianjin St, Changchun 130012, Jilin, Peoples R China.. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine
N,N’-Acetals are sensitive compounds, and the challenging asymmetric synthesis of acyclic N,N’-acetals by the general addition of amines to ketimines has never been reported so far. In this study, highly enantioselective addition of aryl amines to isatin-derived ketimines catalyzed by chiral urea derived from quinine was developed. A series of new acyclic N,N’-acetals were constructed by this protocol in high to excellent yields (78-99%) and high to excellent enantioselectivities (76-96% ee).
