Chiral (1)H NMR of Atropisomeric Quinazolinones With Enantiopure Phosphoric Acids
A chiral phosphoric acid promoted enantioselective NMR analysis of atropisomeric quinazolinones was described, in which a variety of racemic arylquinazolinones such as afloqualone and IC-87114 were well recognized with up to 0. 21 ppm ΔΔδ value. With this method, the optical purities of different no...
