Bio-inspired asymmetric aldehyde arylations catalyzed by rhodium-cyclodextrin self-inclusion complexes.

Transition-metal catalysts are powerful tools for carbon-carbon bond-forming reactions that are difficult to achieve using native enzymes. Enzymes that exhibit inherent selectivities and reactivities through host-guest interactions have inspired widespread interest in incorporating enzymatic behavior into transition-metal catalytic systems that highly efficiently produce enantiopure compounds. Nevertheless, bio-inspired transition-metal catalysts that are highly enantioselective and reactive have rarely been reported.
