Book excerpt: Part I of this dissertation presents the efforts directed towards the total synthesis of batrachotoxin. The general approach focuses on the construction of the C ring of the steroid backbone through two carbon-carbon bond forming reactions. This approach breaks the complex natural product into two more approachable pieces. The AB ring system was accessed from the Hajos-Parish ketone and was coupled to the elaborated D ring by a conjugate addition/Claisen rearrangement sequence to form one of the desired carbon-carbon bonds. Extensive effort has been made in an attempt to cyclize the C ring.Part II describes the development of a new approach to the synthesis of substituted pyridines. The method aims to provide a reliable synthesis of a diverse scope of substituted pyridines through a concise three step procedure. Readily available enones are first converted into 1,5-dicarbonyls through a two-step Sakurai allylation/oxidative cleavage sequence, which is followed by subsequent cyclization to the corresponding pyridine using hydroxylamine hydrochloride. A variety of substituted pyridines have been synthesized using this method.

Available in PDF, EPUB and Kindle. Book excerpt: Presents both the fundamental concepts and the most recent applications in solid-phase organic synthesis With its emphasis on basic concepts, Solid-Phase Organic Synthesis guides readers through all the steps needed to design and perform successful solid-phase organic syntheses. The authors focus on the fundamentals of heterogeneous supports in the synthesis of organic molecules, explaining the use of a solid material to facilitate organic synthesis. This comprehensive text not only presents the fundamentals, but also reviews the most recent research findings and applications, offering readers everything needed to conduct their own state-of-the-art science experiments. Featuring chapters written by leading researchers in the field, Solid-Phase Organic Synthesis is divided into two parts: Part One, Concepts and Strategies, discusses the linker groups used to attach the synthesis substrate to the solid support, colorimetric tests to identify the presence of functional groups, combinatorial synthesis, and diversity-oriented synthesis. Readers will discover how solid-phase synthesis is currently used to facilitate the discovery of new molecular functionality. The final chapter discusses how using a support can change or increase reaction selectivity. Part Two, Applications, presents examples of the solid-phase synthesis of various classes of organic molecules. Chapters explore general asymmetric synthesis on a support, strategies for heterocyclic synthesis, and synthesis of radioactive organic molecules, dyes, dendrimers, and oligosaccharides. Each chapter ends with a set of conclusions that underscore the key concepts and methods. References in each chapter enable readers to investigate any topic in greater depth. With its presentation of basic concepts as well as recent findings and applications, Solid-Phase Organic Synthesis is the ideal starting point for students and researchers in organic, medicinal, and combinatorial chemistry who want to take full advantage of current solid-phase synthesis techniques.

Available in PDF, EPUB and Kindle. Book excerpt: The area of food toxicology currently has a high profile of interest in the food industry, universities, and government agencies, and is certainly of great concern to consumers. There are many books which cover selected toxins in foods (such as plant toxins, mycotoxins, pesticides, or heavy metals), but this book represents the first pedagogic treatment of the entire range of toxic compounds found naturally in foods or introduced by industrial contamination or food processing methods. Featuring coverage of areas of vital concern to consumers, such as toxicological implications of food adulteration (as seen in ethylene glycol in wines or the Spanish olive oil disaster) or pesticide residues, Introduction to Food Toxicology will be of interest to students in toxicology, environmental studies, and dietetics as well as anyone interested in food sources and public health issues. The number of students who are interested in toxicology has increased dramatically in the past several years. Issues related to toxic materials have received more and more attention from the public. The issues and potential problems are reported almost daily by the mass media, including television, newspapers, and magazines. Major misunderstandings and confusion raised by those reports are generally due to lack of basic knowledge about toxicology among consumers. This textbook provides the basic principles of food toxicology in order to help the general public better understand the real problems of toxic materials in foods. - Principles of toxicology - Toxicities of chemicals found in foods - Occurrence of natural toxins in plant and animal foodstuffs - Food contamination caused by industry - Toxic chemicals related to food processing - Food additives - Microbial toxins in foods

This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nicotinoids are the most important new class of pesticides, joining the organophosphorus compounds, methylcarbamates, and pyrethroids as the major insecticides. Recently, imidacloprid and related nicotinoids have begun replacing organophosphorus and methylcarbamate compounds as insecticides to control insect pests on major crops. Nicotinoids act on the nicotinic acetylcholine receptor, as does naturally occurring nicotine, but with remarkable effectiveness against insects while being safe for mammals; they are quickly degraded and do not persist in the environment. This volume describes the relationship of nicotinoids to botanical insecticidal alkaloids, their discovery and development as insecticides, and the prospects for their expanded use and for the development of resistance. This book is the first to provide concise, comprehensive information on nicotinoids, their chemistry, mode of action, metabolism, and application in agriculture.

Book excerpt: Since the middle of the Sixties, new types of formulation for biologically active com pounds have been developed, which have been introduced into the literature under the term Controlled Release Formulations (CRF). Stimulated by results from former and successful pharmaceutical research, which was engaged in the production of prepa rations with protracted effects (introduction onto the market in the year 1952 of D amphetamine in the form of pellets, coated to varying degrees with fats and waxes) 1), experiments were carried out to transfer the prolongation of effectiveness to pesticidal substances also, by means of a depot formulation. Initial work was concerned with the production of protective coatings for sonar systems in marine ecosystems. By means of antifouling paints or rubber coatings containing tri-n-butyl-tin oxide (TBTO), the growth of marine organisms on sonar domes, buoys and hulls in the water could be effectively prevented 2. 3). Controlled release formUlations of pesticides are defined as depot systems which continuously release their toxic constituents into the environment over a specified period of time (usually months to years) 4). According to this definition, such formu lations can be successfully employed where a chronic exposure to biologically active compounds is required over a longer period. The following hypothetical example is intended to illustrate this 5). In Fig. 1, the duration of activity of a non-persistent pesticide with a loss rate under environmental conditions of t1/2 = 15 days, is graphically illustrated.
