Searching with a beady eye: A high‐throughput, on‐bead screen of rhodiummetallopeptide catalysts was developed in a 96‐well format for asymmetriccyclopropanation. Different sequences of natural L‐amino acids have been identified that produce opposite product enantiomers (see picture). In addition to styrene derivatives, high enantioselectivity is observed for vinyl ether and vinyl amine derivatives
