Development of facile synthetic methods for various disubstituted pyrroles from pyrrolidine and 2-substituted 1-pyrrolines is reviewed based on our recent findings. Various 1,3-disubstituted pyrroles were synthesized by reaction of pyrrolidine and aldehyde heating without any catalyst. On the other hand, 2,3-disubstituted pyrroles were synthesized from 2-substituted 1-pyrrolines by a sequece involving its aldol-type condensation with aldehyde and subsequent base-catalyzed double-bond isomerization. Application of the former method to one-pot synthesis of a pyrrolocyclophane and preparation of N-substituted indoles from indoline and aldehydes is disclosed. Some pyrrole products by the latter method were transformed into dipyrrin derivatives via their pyrrole-2-carbaldehydes, and chemical and structural properties of the dipyrrin derivatives are described.
