Chiral Phosphorous Based Ligands in Earth-Abundant Transition Metal Catalysis summarizes the most significant progress in the field of chiral phosphine ligand chemistry and a broad range of earth-abundant transition metal/chiral phosphine ligand-catalyzed enantioselective transformations. The book provides an authoritative and in-depth understanding of important topics about asymmetric catalysis based on earth-abundant transition metals/chiral phosphine ligands, making it ideal for organic chemistry researchers working in the field of asymmetric catalysis, synthetic methodologies and total synthesis.The development of new chiral phosphine ligands to achieve precise stereo control in many earth-abundant transition metal-catalyzed reactions is a very important field in organic synthesis, materials science and medicinal chemistry. The asymmetric synthesis promoted by transition metal/chiral phosphine ligands provides one of the most ideal ways to produce valuable optically active chemicals. Includes a discussion of state-of-the-art asymmetric organic reactions mediated by earth-abundant transition metals and chiral phosphine ligands Features the progress and the prospect of chiral phosphine ligands in asymmetric transition metal catalysis Covers the asymmetric reactivity modes of earth-abundant transition metals and phosphine ligands

Describes the Efficient and Practical Methods for the Synthesis of Various Functionalized Organic Molecules From Enynes Through Different Transformations In the past decades, enynes have become increasingly popular among organic chemists due to their unique structure and diverse transformations such as cycloaddition, cyclization, which has led to a variety of cyclic products. Modern Enyne Chemistry presents efficient and practical methods for the synthesis of various functionalized organic molecules from enynes through different transformations such as cycloadditions, cycloisomerization, cyclizations, and tandem reactions. Authored by a well-qualified industry professional, the work is broken down into seven chapters and includes sample topics such as: The synthesis of conjugated enynesDiverse transformationsThe synthetic power of enynes for rapid assembly of complex molecular structuresA mechanistic rationale to aid readers in understanding the reactions together with the new transformations in unsaturated compoundsFor organic chemists, natural products chemists, and biochemists, this book serves as a complete reference work for understanding both modern and historical research on the topic of enynes, plus their numerous applications to today’s industries.
