Wang, Guan-Jun published the artcileHighly Site- and Enantioselective N-H Functionalization of N-Monosubstituted Aniline Derivatives Affording Pyrazolones Bearing a Quaternary Stereocenter, Quality Control of 5961-59-1, the main research area is alkylaniline pyrazolone chiral phosphoric acid regioselective enantioselective alkylation; arylalkyl aminopyrazolone preparation.
Chiral phosphoric acid catalyzed the regio- and enantioselective N-H functionalization of N-alkylaniline with pyrazolones derived ketimines as electrophiles, providing a variety of chiral pyrazolones containing a tetrasubstituted stereocenter bearing a new N,N’-acetal motif in excellent yields and high enantioselectivities was reported. This strategy was featured by low catalyst loading, mild conditions, and high efficiency and selectivity.
Chinese Journal of Chemistry published new progress about Alkylation catalysts, stereoselective. 5961-59-1 belongs to class isoquinoline, name is 4-Methoxy-N-methylaniline, and the molecular formula is C8H11NO, Quality Control of 5961-59-1.
