The reaction of anions of the acyclic imides 1 with the cyclopropylphosphonium salt 2 yields ethyl 1-acyl-Δ2-pyrroline-3-carboxylates 3, substituted in position 2, which can be dehydrogenated to yield the corresponding 1-acylpyrroles 4 and subsequently deacylated to give the pyrroles 5.The scope of the reaction is discussed.
