Complex tricylic aziridines can be prepared from simple pyrroles by UV irradiation. In their Communication on page 1499 ff., K. I. Booker-Milburn and co-workers show that the reaction proceeds by a two-stage photochemical sequence that involves [2+2] cycloaddition and rearrangement, and that the scale of the reaction can be increased using a customized FEP flow reactor.
