A substoichiometric copper iodide catalysed synthesis of indene and dihydronaphthalenederivatives has been accomplished. This protocol is compatible with functional groups, and results in various scaffolds of indene and dihydronaphthalenederivatives in good to high yields. By employing this protocol, a functionalised cyclohexenone derivative is also achieved.

A facile synthesis of potentially useful 1-diiodomethylene indanes and cyclopentanes from the regioselective cyclization of acetylenic malonates with the combination of iodosobenzene with tetrabutylammonium iodide in 2,2,2-trifluoroethanol is reported.
Cascade Reactions: A Multicomponent Approach to Functionalized Indane Derivatives by a Tandem Palladium- Catalyzed Carbamoylation/Carbocylization Process
AbstractA novel, multicomponent and stereoselective approach to functionalized indane derivatives is reported. It is based on a tandem process consisting of Pd‐catalyzed oxidative carbamoylation of 2‐(2‐ethynylbenzyl)malonates with carbon monoxide, a secondary amine, and oxygen (with formation of a propiolamide intermediate), followed by carbocyclization, occurring through intramolecular addition of an in situ formed carbanion to the propiolamide moiety.magnified image
