elimination.
In summary, we have established an efficient method for
accessing fused dibenzoisoquinolinediones and dibenzo-
isoquinolinones by Pd-catalyzed domino cyclization of
alkene-tethered aryl iodides with o-bromobenzoic acids. The
reaction is accomplished through a sequence of Heck
cyclization, C−H activation, and decarboxylation. Importantly,
this approach displays high regioselectivity and good
compatibility of substrates via the insertion of aromatic rings
from o-bromobenzoic acids. Further studies toward exploring
this type of domino reaction are underway in our laboratory.
