A wide range of multisubstituted 1-indanones of potential pharmaceutical use were synthesized in a one-pot fashion in moderate to excellent yields via palladium catalysis in ethylene glycol. The Heck reaction first installs an enol functionality on the aromatic ring; this is followed by an ethylene glycol promoted aldol-type annulation with a neighboring carbonyl group, resulting in the formation of various 1-indanones.

We report a facile and highly efficient method that copper-catalyzed intramolecularannulation to synthesize 3-hydroxy-1-indanones employing simple 2-ethynylbenzaldehyde as starting materials was achieved successfully. This protocol provided a simple synthetic approach to afford 3-hydroxy-1-indanones under mild conditions in good to excellent yields.
