Chen, Gong published the artcileDirhodium-Catalyzed Chemo- and Site-Selective C-H Amidation of N,N-Dialkylanilines, Safety of Ethyl 4-dimethylaminobenzoate, the publication is Synlett (2021), 32(7), 728-732, database is CAplus.
A method for dirhodium-catalyzed C(sp3)-H amidation of N,N-dimethylanilines was developed. Chemoselective C(sp3)–H amidation of N-Me group proceeded exclusively in the presence of C(sp2)-H bonds of the electron-rich aromatic ring. Site-selective C(sp3)-H amidation proceeded exclusively at the N-Me group of N-methyl-N-alkylaniline derivatives with secondary, tertiary, and benzylic C(sp3)-H bonds α to a nitrogen atom.
Synlett published new progress about 10287-53-3. 10287-53-3 belongs to esters-buliding-blocks, auxiliary class Amine,Benzene,Ester, name is Ethyl 4-dimethylaminobenzoate, and the molecular formula is C11H15NO2, Safety of Ethyl 4-dimethylaminobenzoate.
