A General Synthesis of Pyrroles from Aldehydes and Ketones
Baldwin, Jack E.,Bottaro, Jeffrey C.
, p. 624 - 625 (1982)
The azines of enolisable aldehydes and ketones are converted into pyrroles via thermal rearrangement of the derived benzoyl derivatives and subsequent hydrazinolysis of the resulting N-benzoylpyrroles.
Regioselective substituent effects upon the synthesis of dipyrrins from 2-formyl pyrroles

The synthesis of symmetric α-free meso-H-dipyrrin hydrobromides from 5-H-2-formyl pyrroles was investigated. The self-condensation produces regioisomeric dipyrrins through adoption of two mechanistic pathways. The key difference between the two pathways lies in which position of the pyrrole directs nucleophilic attack. Through a systematic study involving various substituted and (or) isotopically labelled 5-H-2-formyl pyrroles, we herein provide evidence to suggest that not only do two mechanistic pathways exist, but the steric bulk of the substituent adjacent to the 5-unsubstituted position influences which pathway dominates.
