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.

Be more accepting: Indenone azines, in which two indene units are cross-conjugated by an exocyclic azine (C=N−N=C) moiety, have been synthesized in a stereocontrolled manner. The azine moiety makes indenone azines planar structure and gives enhanced electron-accepting character, thus making them promising candidates as electron-accepting building blocks.
