Polyfunctionalized beta-fluoropyrrole can be readily prepared from rhodium(II) acetate-catalyzed intramolecular N-H insertion reaction of delta-amino-gamma,gamma-difluoro-alpha-diazo-beta-ketoesters. A cyanomethylene group can be introduced at C-3 of the pyrrole ring through the Wittig reaction of the diazo compounds followed by rhodium(II)-catalyzedintramolecular N-H insertion reactions.
