The Chichibabin pyridine synthesis (/ˈtʃiːtʃiːˌbeɪbiːn/) is a method for synthesizing pyridine rings. The reaction involves the condensation reaction of aldehydes, ketones, α,β-Unsaturated carbonyl compounds, or any combination of the above, with ammonia.[1] It was reported by Aleksei Chichibabin in 1924.[2][3]
Methyl-substituted pyridines, which show widespread uses among multiple fields of applied chemistry, are prepared by this methodology.[4]
