Available in PDF, EPUB and Kindle. Book excerpt: A compilation of recent advances and applications in asymmetric catalysis The field of asymmetric catalysis has grown rapidly and plays a key role in drug discovery and pharmaceuticals. New Frontiers in Asymmetric Catalysis gives readers a fundamental understanding of the concepts and applications of asymmetric catalysis reactions and discusses the latest developments and findings. With contributions from preeminent scientists in their respective fields, it covers: * "Rational" ligand design, which is critically dependent on the reaction type (reduction, oxidation, and C-C bond formation) * Recent findings on activation of C-H bonds, C-C bonds, and small molecules (C=O, HCN, RN=C, and CO2) and the latest developments on C-C bond reorganization, such as metathesis * Advances in "chirally economical" non-linear phenomena, racemic catalysis, and autocatalysis * Some of the recent discoveries that have led to a renaissance in the field of organocatalysis, including the development of chiral Brönstead acids and Lewis acidic metals bearing the conjugate base of the Brönstead acids as the ligands and the chiral bi-functional acid/base catalysts The book ends with a thought-provoking perspective on the future of asymmetric catalysis that addresses both the challenges and the unlimited potential in this burgeoning field. This is an authoritative, up-to-date reference for organic chemists in academia, government, and industries, including pharmaceuticals, biotech, fine chemicals, polymers, and agriculture. It is also an excellent textbook for graduate students studying advanced organic chemistry or chemical synthesis.

Download or read book Synthesis of Diene and Dienophile Substrates for In-vitro Selection of RNA-hetero-diels-alder Catalysts written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The hetero-Diels-Alder reaction provides a general and facile entry for the synthesis of six-membered heterocyclic structures, which serve as precursors for a host of biologically active compounds. Although there are a wide variety of heterodienes and heterodienophiles available for synthetic applications, our research focuses on the cycloaddition of activated 1,3-butadienes with an activated aromatic aldehyde dienophile and an unactivated aliphatic aldehyde dienophile. Cycloadditions of this type provide access to an important class of compounds known as dihydropyrans, which are useful intermediates for the preparation of carbohydrates and many other biologically active compounds. Synthesis of pyrans by HDA cycloaddition has been limited to the reaction of either highly electron rich dienes (e.g. Danishefsky's diene) with a broad range of aldehydes or highly activated aldehydes (e.g. glyoxylates) with dienes of varying activity. Currently there are few examples of cycloadditions between unactivated aldehyde dienophiles and dienes that are less activated than Danishefsky's diene. Also, the catalysts currently available for this transformation provide access to only one of two possible regioisomers and provide a single diastereomer almost exclusively. If efficient catalysts for the uncommon HDA regio- and stereoisomers are attainable, then we believe that in vitro selection of these catalysts from a pool of 10∧14 random RNA sequences will provide invaluable clues as to structural properties necessary for such catalysts. To this end, we have prepared novel dienes and dienophiles suitable for in vitro selection of new RNA biocatalysts capable of assembling novel heterocyclic products via a hetero-Diels-Alder cycloaddition.
