Key words
Catellani reaction - palladium catalysis - planar chiral metallocenes - remote C–H activation
Significance
The synthesis of planar 1,3-disubstituted chiral metallocenes via palladium-catalyzed remote C–H activation is reported. The reaction features high enantioselectivities and good functional group tolerance. Aryl iodides as well as bromides serve as compatible coupling partners.

Comment
An initial directed enantiodetermining C–H activation at the ortho-position, enabled by a chiral mono-N-protected natural amino acid ligand, is followed by a C–H activation of the remote meta-position using a bridgehead-substituted norbornene mediator, akin to the Catellani reaction.
