Ashizawa, Tomoko; Yamada, Tohru published the artcile< Catalytic atropo-enantioselective preparation of axially chiral biaryl compounds>, Category: chiral-phosphine-ligands, the main research area is biaryl lactone methanol chiral silver catalyst triisobutylamine ring opening; ester biaryl hydroxy derivative atropo stereoselective preparation; silver tetrafluoroborate binap derivative dynamic kinetic resolution catalyst.
The atropo-enantioselective ring-opening of biaryl lactones with methanol was catalyzed by an optically active AgBF4-phosphine complex to afford axially chiral biaryl compounds The addition of triisobutylamine provided a rate acceleration and increase in enantioselectivity in the reaction. Various types of axially chiral biaryl compounds were obtained with high enantioselectivity.
