Abstract

Due to the diversity of applications and the broad distribution of pyridine derivatives in nature, numerous synthetic methods for these heterocyclic systems have been investigated. [1] Our studies in the field of ternary iminium salts led to the development of efficient one-pot reactions yielding a wide range of functionalized pyridines, bipyridines and terpyridines. [2] All these reactions are based on the ability of Mannich bases 1 to form α,β-unsaturated ...
