Access to acridones by tandem copper(<scp>i</scp>)-catalyzed electrophilic amination/Ag(<scp>i</scp>)-mediated oxidative annulation of anthranils with arylboronic acids
An efficient and practical approach for the synthesis of medicinally important acridones was developed from anthranils and commercially available arylboronic acids by a tandem copper(I)-catalyzed electrophilic amination/Ag(I)-mediated oxidative annulationstrategy. This new and straightforward protocol displayed a broad substrate scope (25 examples) and high functional group tolerance. What's more
