Available in PDF, EPUB and Kindle. Book excerpt: [Greek letter beta]-Lactones, important targets in synthesis, are integral structural features of many biologically active molecules such as Salinosporamide A, Omuralide, panclicin D and 1233A. [Greek letter beta]-Lactones have also been employed in the synthesis of many natural products. Two important pathways to access [Greek letter beta]-Lactones from ketenes have been reported in the literature. The first pathway to [Greek letter beta]-lactones is through dimerization of ketenes, and the other pathway is through a formal [2+2] cycloaddition of ketenes and aldehydes or ketones. While the asymmetric homodimerization of certain aldoketenes has been reported by Calter and co-workers, our group and Ye's group have communicated independently results in the asymmetric homodimerization of ketoketenes. We have found that Josiphos phosphine catalysts (10 mol% catalyst loading) are optimal nucleophilic catalysts for homodimerization of alkylarylketenes with high asymmetic induction (up to 96% ee), and dialkylketenes (up to 99% yield). We also investigated phosphine-catalyzed formal [2+2} cycloaddition of alkylarylketoketenes and aldehydes and found the chiral diphosphine catalyst R-BINAPHANE to be the optimal catalyst in terms of enantioselectivity (up to 99% ee), diastereoselectivity (dr up to 99:1) and yield. Only a few isolated cases of regioselective heterodimerization of ketenes have been reported in the literature and those have used special ketenes. We have developed a method for accessing ketene heterodimer [Greek letter beta]-lactones in a highly regioselective and enantioselective fashion through the cinchona alkaloid-catalyzed formal [2+2] cycloaddition of various aldoketenes (generated in situ) with ketoketenes (alkylarylketenes and dimethylketene) or trimethylsilylketene. The ketene heterodimers are formed in good to excellent yields (up to 90%) and with excellent enantioselectivities (up to 99%).

Available in PDF, EPUB and Kindle. Book excerpt: The Conservation of Orbital Symmetry examines the principle of conservation of orbital symmetry and its use. The central content of the principle was that reactions occur readily when there is congruence between orbital symmetry characteristics of reactants and products, and only with difficulty when that congruence does not obtain—or to put it more succinctly, orbital symmetry is conserved in concerted reaction. This principle is expected to endure, whatever the language in which it may be couched, or whatever greater precision may be developed in its application and extension. The book opens with a review of the elementary aspects of the molecular orbital theory of bonding. This is followed by separate chapters on correlation diagrams, the conservation of orbital symmetry, theory of electrocyclic reactions, theory of cycloadditions and cycloreversions, and theory of sigmatropic reactions. Subsequent chapters deal with group transfers and eliminations; secondary conformational effects in concerted cycloaddition reactions; and generalized selection rules for pericyclic reactions.

Book excerpt: The ASI workshop on "Selectivities in Lewis Acid Promoted Reactions" held in the Emmantina-Hotel in Athens-Glyfada, Greece, October 2-7, 1988 was held to bring some light into the darkness of Lewis acid induced processes. As such the workshop reflects some current trends in organic synthesis, where Lewis acids are becoming a powerful tool in many different modern reactions, e.g. Diels-Alder reactions, Ene reactions, Sakurai reactions, and in general silicon and tin chemistry. The objective of this meeting was to bring together most of the world experts in the field to discuss the major reactions promoted by Lewis acids. Organic synthesis will play a major role in this book connected with some fundamental mechanistic work on allylsilane and -tin chemistry. Both natural product synthesis and unnatural molecules are presented in the chapters. The book presents all the 15 invited lectures and the contributions of 15 posters. I am confident that the material presented in this book will stimulate the chemistry, which has been discussed on our meeting, around the world. The meeting and the book were only possible through a grant of the NATO Scientific Affairs Devision and financial support by the following companies: Kali Chemie (Hannover, W-Germany), E. Merck (Darmstadt, W-Germany), Sandoz (Basel, Switzerland), Schering (Berlin, W-Germany).

Book excerpt: Although many books exist on the subject of chiral chemistry, they only briefly cover chiral synthesis and analysis as a minor part of a larger work, to date there are none that pull together the background information and latest advances in one comprehensive reference work. Comprehensive Chirality provides a complete overview of the field, and includes chiral research relevant to synthesis, analytic chemistry, catalysis, and pharmaceuticals. The individual chapters in each of the 9 volumes provide an in depth review and collection of references on definition, technology, applications and a guide/links to the related literature. Whether in an Academic or Corporate setting, these chapters will form an invaluable resource for advanced students/researchers new to an area and those who need further background or answers to a particular problem, particularly in the development of drugs. Chirality research today is a central theme in chemistry and biology and is growing in importance across a number of disciplinary boundaries. These studies do not always share a unique identifying factor or subject themselves to clear and concise definitions. This work unites the different areas of research and allows anyone working or researching in chiral chemistry to navigate through the most essential concepts with ease, saving them time and vastly improving their understanding. The field of chirality counts several journals that are directly and indirectly concerned with the field. There is no reference work that encompasses the entire field and unites the different areas of research through deep foundational reviews. Comprehensive Chirality fills this vacuum, and can be considered the definitive work. It will help users apply context to the diverse journal literature offering and aid them in identifying areas for further research and/or for solving problems. Chief Editors, Hisashi Yamamoto (University of Chicago) and Erick Carreira (ETH Zürich) have assembled an impressive, world-class team of Volume Editors and Contributing Authors. Each chapter has been painstakingly reviewed and checked for consistent high quality. The result is an authoritative overview which ties the literature together and provides the user with a reliable background information and citation resource.

Available in PDF, EPUB and Kindle. Book excerpt: Spurred by the desire to make chemistry a sustainable and "greener" technology, the field of organocatalysis has grown to become one of the most important areas in synthetic organic chemistry. Organic catalysts can often replace potentially toxic metal catalysts and allow reactions to proceed under mild reaction conditions, thereby saving energy costs and rendering chemical processes inherently safer. More importantly perhaps, organocatalysis offers a complementary reactivity in many instances leading to increased versatility. This Handbook describes 126 key reagents for organocatalytic reactions and will be especially useful for professionals in the area of sustainable chemistry, medicinal research, as well as synthetic organic chemists working in academia and the pharmaceutical industry. All the information compiled in this volume is also available in electronic format on Wiley Online Library. The 126 reagents represented here are but a small fraction of the ca. 5,000 reagents available in the electronic Encyclopedia of Reagents for Organic Synthesis (e-EROS). e-EROS offers various search interfaces to locate reagents of interest, including chemical structure, substructure and reactions search modes. e-EROS is updated regularly with new and updated entries.
