Stereoselective organocatalytic C−C bond formations that tolerate N‐heterocycles are valuable since these moieties are common motifs in numerous chiral bioactive compounds. Such transformations are, however, challenging since N‐heterocyclic moieties can interfere with the catalytic reaction. Here, we present a peptide that catalyzes conjugateaddition reactions between aldehydes and nitroolefins bearing a

An enzyme and a peptide catalyze—in an aqueous buffer—a two-step cascade reaction with high chemo- and stereoselectivity in one pot. The optimization of the modular peptide catalyst and the identification of common reaction conditions were key for bringing the two worlds of enzyme and peptide catalysis together.
