Catalytic regioselective synthesis of structurally diverse indene derivatives from N-benzylic sulfonamides and disubstituted alkynes

An unprecedented protocol has been developed for the regioselective synthesis of structurally diverse indene derivatives from readily accessible N-benzylic sulfonamides and disubstituted alkynes through FeCl 3-catalyzed cleavage of sp3 carbon-nitrogen bonds to generate benzyl cation intermediates. In the presence of 10 mol % of FeCl 3, a broad range of N-benzylic sulfonamides smoothly react with internal alkynes, alkynylcarbonyl compounds, alkynyl chalcogenides, or alkynyl halides to afford various functionalized indene derivatives with extremely high regioselectivity.

Formation of 2-Substituted 1,3-Diphenylindenes by an N-Bromosuccinimide Promted Dehydrocyclization of 2-Substituted 1,3,3-Triphenyl-1-propenes

The reactions of a series of 2-substituted 1,3,3-triphenyl-1-propenes with N-bromosuccinimide (NBS) afforded the corresponding 2-substituted 1,3-diphenylindenes in moderate yields.A reaction mechanism involving a novel free-radical intramolecular ring-clo
