A Photoinduced Cobalt-Catalyzed Synthesis of Pyrroles through <i>in Situ</i>-Generated Acylazirines

Tetrasubstituted pyrroles can be synthesized in a one-pot procedure from isoxazoles. The process includes the photoinduced <i>in situ</i> formation of acylazirines combined with a subsequent cobalt­(II)-catalyzed ring expansion with 1,3-diketones
