This text then describes trimethysilyldiazomethane as a stable and safe substitute for hazardous diazomethane. Other chapters consider the usefulness of trimethysilyldiazomethane in organic syntheses. This book discusses as well that malonic amides, silylenol ethers, malonic esters, and tetra-donor-substituted allenes serve as synthetic equivalents for the dianions of malonic esters, ketones, and malonic amides. The final chapter deals with the synthesis of biologically-active compounds, which has been one of the major challenges for organic chemists. This book is a valuable resource for practicing synthetic chemists. |

| list of synthons and synthetic equivalents: Elements of Synthesis Planning R. W. Hoffmann, 2009-01-07 Synthesis is at the core of organic chemistry. In order for compounds to be studied—be it as drugs, materials, or because of their physical properties— they have to be prepared, often in multistep synthetic sequences. Thus, the target compound is at the outset of synthesis planning. Synthesis involves creating the target compound from smaller, readily available building blocks. Immediately, questions arise: From which bui- ing blocks? In which sequence? By which reactions? Nature creates many highly complex “natural products” via reaction cascades, in which an asso- ment of starting compounds present within the cell is transformed by speci c (for each target structure) combinations of modular enzymes in speci c - quences into the target compounds [1, 2]. To mimic this ef ciency is the dream of an ideal synthesis [2]. However, we are at present so far from - alising such a “one-pot” operation that actual synthesis has to be achieved via a sequence of individual discrete steps. Thus, we are left with the task of planning each synthesis individually in an optimal fashion. Synthesis planning must be conducted with regard for certain speci - tions, some of which are due to the structure of the target molecule, and some of which relate to external parameters such as costs, environmental compatibility, or novelty. We will not consider these external aspects in this context. Planning of a synthesis is based on a pool of information regarding chemical reactions that can be executed reliably and in high chemical yield. |

Chapter five describes many new methods for the construction of quinoxaline macrocycles, which are important in applications such as optical devices and materials. The final chapter reviews all previously known rearrangements of heterocyclic systems that lead to benzimidazole derivatives. Mamedov critically analyses these transformations to reveal a novel acid-catalyzed rearrangement of quinoxalinones giving 2-heteroarylbenzimidazoles and 1-heteroarylbenzimidazolones in the presence of nucleophilic reactants (MAMEDOV Heterocycle Rearrangement).

Meister, Bettina M. Ruff, Sabilla Zhong, 2013-02-28 The biological activity of mycotoxins ranges from weak and/or sometimes positive effects, such as antibacterial activity (see penicillin derivatives derived from Penicillium strains) to strong mutagenic (e. g. aflatoxins, patulin), carcinogenic (e. g. aflatoxins), teratogenic, neurotoxic (e. g. ochratoxins), nephrotoxic (e. g. fumonisins, citrinin), hepatotoxic, and immunotoxic (e. g. ochratoxins, diketopiperazines) activity. Nowadays, many laboratories around the world are specialized in the detection of mycotoxins in food products and contaminated material found in housing. In this volume, a focus on the most important classes of mycotoxins is provided and their chemistry of the last ten years is discussed. In each Section, the individual biological impact is outlined.

| list of synthons and synthetic equivalents: Cross-Coupling Reactions S.L. Buchwald, 2002-01-11 In 1972, a very powerful catalytic cycle for carbon-carbon bond formation was 2 first discovered by the coupling reaction of Grignard reagents at the sp -carbon. Over the past 30 years, the protocol has been substantially improved and expanded to other coupling reactions of Li,B,N,O,Al,Si,P,S,Cu,Mn,Zn,In,Sn, and Hg compounds. These reactions provided an indispensable and simple methodology for preparative organic chemists. Due to the simplicity and rel- bility in the carbon-carbon, carbon-heteroatom, and carbon-metalloid bo- formations,as well as high efficiency of the catalytic process,the reactions have been widely employed by organic chemists in various fields. Application of the protocol ranges from various syntheses of complex natural products to the preparation of biologically relevant molecules including drugs, and of sup- molecules, and to functional materials. The reactions on solid surfaces allow robot synthesis and combinatorial synthesis. Now, many organic chemists do not hesitate to use transition metal complexes for the transformation of org- ic molecules. Indeed, innumerable organic syntheses have been realized by the catalyzed reactions of transition metal complexes that are not achievable by t- ditional synthetic methods. Among these, the metal-catalyzed cross-coupling reactions have undoubtedly contributed greatly to the development of such a new area of “metal-catalyzed organic syntheses”. An excellent monograph for the cross-coupling reactions and other met- catalyzed C-C bond-forming reactions recently appeared in Metal-catalyzed Cross-coupling Reactions (Wiley-VCH,1998). |

| list of synthons and synthetic equivalents: The Chemistry of the Metal Carbon Bond, Volume 4 Frank R. Hartley, 1987 The Chemistry of the Metal-Carbon Bond is a multi-volume work within the well established series of books covering The Chemistry of Functional Groups. It aims to cover the chemistry of the metal-carbon bond as a whole, but lays emphasis on the carbon end. It should therefore be of particular interest to the organic chemist. This fourth volume is concerned with the use of organometallic compounds in organic synthesis. It includes material concerned with carbon-carbon bond formation together with chapters concerned with the formation of carbon-hydrogen and other carbon- element bonds. The material is divided into two parts: the first part is concerned with the preparation of the main group organometallic compounds and their Use in organic synthesis. The second part includes the use of transition metal organometallics in organic synthesis as well as chapters on hydrogenation, saturated carbon-hydrogen bond activation and the rapidly expanding field of supported metal complex catalysts. |
