Abstract
Pd(0)-catalyzed intramolecular C–H alkenylation was achieved with excellent yields and enantioselectivity for the construction of planar chiral ferrocenes. It is compatible with a broad range of substrates and various functional groups. Notably, the enantioselective and diastereoselective synthesis of planar chiral ferrocenes was realized by cascade C–H arylation and alkenylation reaction for the first time. Additionally, the product was easily converted into a N,O-bidentate ligand, showing promising chiral induction in asymmetric alkynylation of 1-naphthaldehyde.
