furnish polysubstituted indolizines. Overall, the indolizine core can be constructed from a pyridine, two aldehydes, and a nitroalkane, and no undesired functional groups remain in the products. When bromoacetonitrile was used for the N-alkylation, indolizine-3-carbonitriles were obtained instead. The pyridine component may be replaced by other azines, giving rise to relatedheterocyclic systems.
