Molecular acrobatics: Irradiation of N‐butenyl‐substituted pyrroles that bear an electron‐withdrawing group leads to complex tricyclicaziridines through an unprecedented photocycloaddition–rearrangement sequence. Gram quantities of these complex products could be produced by using a bespoke flow reactor (see picture, FEP=fluorinated ethylene propylene).
