Building Molecules by a Self-Replicator That Catalyzes Acyl Hydrazone Formation. [PDF]

Angew Chem Int Ed Engl
A self‐replicator efficiently catalyzes the formation of acyl hydrazone bonds between a set of different substrates. In addition to previously reported (bond‐breaking) catalytic activity, this renders the self‐replicator highly promiscuous, which is a good starting point for Darwinian experiments en route to de‐novo life.
