N,N-Dibenzylaminocyclopropyl ketimines formed as intermediates upon treatment of 2-lithiated N,N-dibenzylcyclopropylamines with nitriles, being donor-acceptor-substituted cyclopropanes, immediately underwent ring-enlarging rearrangement and 1,2-elimination of dibenzylamine to produce 2-substituted pyrroles in good yields (14 examples, 55-80%).

, p. 3141 - 3151 (2007/10/02)
Two short and efficient synthetic approaches for -mostly unknown- 2-arylpyrroles are presented.The key intermediates 3 are conveniently obtained from commercially available acetophenones 5 (method I) or benzoic acid derivatives 10, 11 (method II).
