A Chiral Metal Photocatalyst Architecture for Highly Enantioselective Photoreactions.

A light in dark places: The discovery of catalysts that can both promote photochemical reactions and control their stereochemistry has been regarded as a central challenge in photochemical synthesis for several decades. The discovery of chiral-at-metal complexes that seem particularly successful in this context is an exciting new development that may provide a general solution to this long-standing problem.
