3-dicarbonyls 2 using ammonium acetate as a nitrogen source. The axialchirality of bipyrrole was anticipated from the X-ray crystal structure and DFT calculations and confirmed by separating the racemates on a chiral column and subsequent CDspectra of the enantiomers. The absoluteconfiguration of the enantiomers was achieved by theoretical CDspectra calculation using the ZINDO method.
