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.

Molybdate sulfuric acid (MSA) has been found as an efficient and reusable solid acid catalyst for the synthesis of new 2,3,4,5-tetrasubstituted pyrroles via a novel [2+2+1] strategy. Thus, one-pot three-component reaction of benzoin derivatives, 1,3-dicar
