Synthesis of Six- and Seven-Membered Heterocycles: The Role of DMF and its Synthesis compares different synthetic approaches using DMF, including the advantages and disadvantages of those reactions, green methods, and the sustainability of reported synthetic methodologies, especially the microwave methods. The book presents several methodologies for the synthesis of six- and seven-membered heterocyclic compounds using dimethylformamide. Users will find the most up-to-date information in this fast-moving field which can be particularly challenging. With DMF drawing the attention of synthetic organic chemists, this book will help readers understand further developments in the uses of dimethylformamide beyond just its use as a polar solvent. As it can be expected that the use of dimethylformamide as a precursor will continue to grow in organic synthesis with new applications in sustainable and green chemistry, this book provides an ideal primer on the topics covered. - Compares different methods, reagents, reaction conditions, advantages and disadvantages - Discusses and compares different methodologies with green techniques - Includes reaction schemes, reaction mechanisms and the structure of reactive intermediates

Synthesis of Five-Membered Heterocycles: Role of DMF as Solvent, Reagent, Catalyst, and Stabilizer helps readers quickly assess possible synthetic approaches. The book's audience, researchers, academic professionals and synthetic chemists both in industry and academia will find detailed information about the synthesis of five-membered heterocyclic compounds using dimethylformamide. Over the years, heterocyclic compounds, especially five-membered, have drawn more attention of pharmaceutical community because of their therapeutic value. The formation of heterocyclic compounds has turned out to be the keystone of synthetic organic chemistry. Dimethylformamide has played an important role in organic synthesis for a long time, and it is frequently utilized as a common solvent for chemical reactions and broadly used in industry as a reagent. It is a unique chemical and can play three other roles in organic chemistry, i.e., as stabilizer, reagent and catalyst. Due to its structure, DMF can participate in several reactions as a versatile building block for several units. - Includes comprehensive descriptions of heterocycle synthesis - Highlights many methods for the synthesis of five-membered heterocyclic compounds using dimethylformamide - Helps readers quickly assess possible synthetic approaches

In the last decade a new era in asymmetric catalysis has been realised by the discovery of L-proline induced chiral enamines from carbonyls. Inspired by this, researchers have developed many other primary catalytic species in situ, more recently secondary catalytic species such as aminals have been identified for use in asymmetric synthesis. High-yielding asymmetric synthesis of bioactive and natural products through mild catalysis is an efficient approach in reaction engineering. In the early days, synthetic chemists mainly focused on the synthesis of complex molecules, with less attention on the reaction efficiency and eco-friendly conditions. Recent investigations have been directed towards the development of atom economy, eco-friendly and enantioselective synthesis for more targeted and efficient synthesis. Building on the momentum of this rapidly expanding research area, Dienamine catalysis for organic synthesis will provide a comprehensive introduction, from the preformed species, in situ generation and onto their applications in the synthesis of bioactive molecules and natural products.
