Abstract
The alkylation of C-H bonds with N-vinylphthalimide by a rhodium-catalyzed reaction of aromatic amides containing an 8-aminoquinoline moiety as the directing group is reported. N-Vinylphthalimide functions as a 2-aminoethylating reagent. The resulting alkylated products can be converted into 3,4-dihydroisoquinolin-1(2H)-one derivatives in a one-pot transformation. Deuterium-labeling experiments suggest that the reaction proceeds through a carbene mechanism.
