title: Synthesis of 2-alkylidenepyrrolidines and pyrroles by condensation of 1,3-dicarbonyl dianions with alpha-azidoketones and subsequent intramolecular Staudinger-aza-Wittig reaction.
abstract: The condensation of 1,3-dicarbonyl dianions with alpha-azidoketones afforded open-chained condensation products that were transformed into pyrroles by Staudinger-aza-Wittig reactions and the subsequent treatment with trifluoroacetic acid.
