Abstract
A highly enantioselective, intramolecular arylcyanation of unactivated olefins via C-CN bond activation has been accomplished using a Ni(0) catalyst, BPh3 as co-catalyst, and TangPHOS as a chiral ligand. Two new C-C bonds and one quaternary carbon stereogenic center are generated in a single synthetic step, converting readily available benzonitriles into 1,1-disubstituted indanes in good yield.
