Dynamic kinetic resolution of biaryl atropisomers by chiral dialkylaminopyridine catalysts†
Abstract
The acylative dynamic kinetic resolution (DKR) of configurationally unstable biaryl atropisomers is achieved by using newly developed chiral dialkylaminopyridine catalysts with fluxional chirality. Various types of biaryl substrates containing phenolic structures were subjected to the DKR to obtain a range of acylated biaryl products with enantiomeric ratios up to 90 : 10.
