Molecular acrobatics: Irradiation of N-butenyl-substituted pyrroles that bear an electron-withdrawing group leads to complex tricyclic aziridines 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).
