Palladium catalyzed, heteroatom-guided C–H functionalization in the synthesis of substituted isoquinolines and dihydroisoquinolines†‡
Abstract
A new approach for the functionalization of C-4 of isoquinolines is reported. The method utilizes palladium catalyzed, hetero-atom guided (or electrophilic metalation) direct arylation via regioselective C–H functionalization of dihydroisoquinolines.
