A new class of chiral cyclopentadienyl rhodium(I) complexes (CpRhI) bearing C2-symmetric chiral bridged-ring-fused Cp ligands was prepared. The complexes were successfully applied to the asymmetric C?H activation reaction of N-methoxybenzamides with quinones, affording a series of chiral hydrophenanthridinones in up to 82 % yield with up to 99 % ee. Interestingly, structure analysis reveals that the side wall of the optimal chiral CpRhI catalyst is vertically more extended, horizontally less extended, and closer to the metal center in comparison with the classic binaphthyl and spirobiindanyl CpRhI complexes, and may thus account for its superior catalytic performance.

New C2-symmetric chiral amines with a rigid bicyclic framework have been synthesized via hydrogenation of monoazides catalyzed by 5% Pd/C in methanol. Enantiomerically pure 2,5-dialkyl-7-thiobicyclo[2.2.1]heptanes were made from readily available materials.
