New trans-β-lactams have been stereoselectively prepared by the reaction of N-pyrrolylpropanoic acid with 2-chloro-1-methylpyridinium iodide and aromatic imines in the presence of triethylamine as a base via in situ generation of methyl-2-(1H-pyrrol-1-yl)ketene as a novel heteroarylketene. The trans-β-lactam was formed either as a single isomer or as the major isomer
