Therefore, extensive efforts have been devoted to their asymmetric synthesis. Recently, transition metal-catalyzed enantioselective C-H activation has become an efficient strategy for the synthesis of planar chiral ferrocenes. We initiated our investigation by testing the asymmetric synthesis of planar chiral ferrocenes by Cu-catalyzed enantioselective C-H alkynylation. Ferrocene carboxamides (1a), bearing a 8-aminoquinoline (Q) first developed by Daugulis was used as the standard substrate to survey our aforementioned design. At the outset of our studies, we investigated various chiral ligands on the reaction of 1a with phenylacetylene 2a in the presence of 20 mol% CuI (Table , see supporting information for details). To our delight, when (S)-BINOL (L1)
