The book "Azaheterocycles Based on α,β-Unsaturated Carbonyls" offers a comprehensive examination of the heterocyclizations of aliphatic and aromatic α,β-unsaturated carbonyl compounds with various binucleophiles. It discusses the synthesis of heterocyclic compounds with three, five, six, and seven members, which are partially hydrated and contain nitrogen. Over the past ten years, interest in these organic compounds has increased as they play a significant role in biological processes and influence various physiological activities. The book highlights the chemical challenges and peculiarities associated with these compounds, including reactivity, chemo- and regioselectivity, as well as tautomerism. The authors, Valentin A. Chebanov, Sergey M. Desenko, and Thomas W. Gurley, provide valuable insights into the synthetic approaches and characteristic properties of these compounds, which are significant for organic chemistry.
