A highly efficient Rh(III)-catalyzed tandem [4+2] annulation to construct functional
dihydroisoquinolinone derivatives with an alkenyl side chain by insertion into an
N–O bond as an internal oxidation process has been achieved. A wide range of 1,3-dienes
as the coupling partners makes this simple methodology even more useful.
Key words
