A Copper-Catalyzed Synthesis of Pyrroles through Photochemically Generated Acylazirines
Paternoga, Jan,Opatz, Till
, p. 7067 - 7078 (2019/11/14)
A synthesis of highly substituted 2,4-diacylpyrroles through a Cu-catalyzed dimerization of acylazirines generated in situ by a photochemical valence isomerization is described. The shown methodology allows the use of simple precursors and a readily avail
A Photoinduced Cobalt-Catalyzed Synthesis of Pyrroles through in Situ-Generated Acylazirines

Tetrasubstituted pyrroles can be synthesized in a one-pot procedure from isoxazoles. The process includes the photoinduced in situ formation of acylazirines combined with a subsequent cobalt(II)-catalyzed ring expansion with 1,3-diketones.
A FACILE ONE-POT SYNTHESIS OF DIACYLPYRROLES
Zen, Shonosuke,Harada, Kazuho
, p. 366 - 369 (2007/10/02)
Various diacylpyrrole derivatives (1) were synthesized in good yields by using β-diketones (4) such as dibenzoylmethane in reaction with primary aliphatic nitro compounds (2) and acetyl chloride.The structures of 1 were established by chemical and spectra
