Here we report the discovery of two homologous groups of pericyclases that catalyse distinct reactions: one group catalyses an Alder-ene reaction that was, to our knowledge, previously unknown in biology; the second catalyses a stereoselective hetero-Diels–Alder reaction. Guided by computational ...
An Alder-ene reaction is a chemical transformation that involves the cyclization of allylamine attached to a 4π-system, resulting in the formation of novel aza-heterocycles.
