An efficient nickel-catalyzed formal [3 + 2]-cycloaddition of 2H-azirines with 1,3-dicarbonyl compounds for the synthesis of tetrasubstituted pyrroles has been developed. This transformation involves cleavage of the C[dbnd]N double bond and the construction of new C[sbnd]C and C[sbnd]N bonds. The reaction employs readily available starting materials, tolerates a wide range of functional groups, and affords tetrasubstituted pyrroles in good to high yields under mild reaction conditions. A gram-scale reaction was performed to demonstrate the scale-up applicability of this synthetic method.

Results of a photochemical study based on product analysis and 337.1-nm laser flash photolysis are reported for several cis- and trans-1,2-dibenzoylethylenes bearing aziridinyl groups at the 1-position.Products isolated from steady-state photolysis suggest facile ring expansion yielding pyrrolines as well as extrusion of alkenes from the aziridine moieties forming nitrene fragments, which subsequently undergo ring closure to give isoxazoles.Laser flash photolysis studies show transient absorption changes, explainable in terms of cis-trans photoisomerisation and formation of azomethine ylides.The latter are also observed upon steady-state irradiation of these aziridinyl-1,2-dibenzoylethylenes in an EPA glass at 77 K.
