Book excerpt: It seems likely that no project of this magnitude is undertaken in the absence of several motivations. This book is no exception. There are, from our perspective, at least two rational reasons for conducting this cataloging and organizational effort. The first of these is the obvious fact that a very large number of macrocyclic polyethers have now been prepared and nowhere is there a comprehensive listing of them. A number of excellent reviews have been published dealing with one or more aspects of macrocycle chemistry, but we felt a great need for a single source listing known compounds. We have, the- fore, attempted to provide such a listing to assist ourselves in keeping track as well as, we hope, helping others in this field. We also felt that there was a need for a survey of methods which have been utilized in the syntheses of these cation binders so that the novice could establish some starting point. Wherever possible, we have also attempted to point to the motivations which en gendered the various syntheses. The somewhat irrational reason which propelled us into this endeavor was the ques tioning of Charlie Morgan who often asked if one or another obscure compound had been synthesized. As often as not, we were uncertain arid now at least have a reference which, if not absolutely complete, will at least save face.

Download or read book Synthetic Multidentate Macrocyclic Compounds written by Reed Izatt and published by Elsevier. This book was released on 2012-12-02 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthetic Multidentate Macrocyclic Compounds attempts to bring together selected chapters in which the authors discuss in depth investigations in important areas of macrocycle research. The chapters deal mainly with macrocyclic compounds (saturated polyethers and their derivatives), and macrobicyclic compounds (cryptates). The book contains six chapters and opens with a first-hand account of the initial synthesis of the cyclic polyethers. This is followed by separate chapters on the synthesis of cyclic polyethers, polyether amines, and polyether sulfides; the synthesis of multidentate compounds; and the structure of synthetic macrocyclic compounds and their cation complexes. Subsequent chapters deal with the rates of reactions and the mechanism by which synthetic macrocyclic ligands complex substrates in solution; and commercial applications of the synthetic macrocyclic ligands. This book is primarily aimed at researchers and students in organic, physical, analytical, and inorganic chemistry, and in chemical engineering. However, it will also be of interest to many in the areas of biology, biochemistry, and physiology. Extensive literature references are found in each chapter.
Download or read book Host Guest Complex Chemistry Macrocycles written by F. Vögtle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific and practical interest in coronands (crown ethers), cryptands, podands as complexing agents for cations as well as for anions and neutral low molecular species is undeniable 1,2). The chemistry of crown compounds is steadily increasing. About 250 original papers dealing with crown chemistry appeared only in 1980. New molecules· with crown ether properties are constantly synthesized and new applications discov,?red. Owing to lack of space, only a small number of the original publications is men tioned here. Thus, in the literature compilation only some, but relevant works are selected for each chapter. Whenever possible, reference is made to reviews or review-like articles alone by means of which origin,al works can be consulted. The reviews given under ref. 1) are considered to be the most relevant. The formulae presented in the figures should be understood as representative structures outlining a specific field. 2 Classification of Oligo-/Multidentate Neutral Ligands and of their Complexes Today, a distinction is made between the classical ring oligoethers (crown ethers) and monocyclic coronands, oligocyclic spherical cryptands and the acyclic podands with respect to topological aspects 3). This classification and the topology are illustrated in Fig. 1, each figure representing the minimum number of donor atoms and chain segments characteristic of each class of compounds. Multidentate mono cyclic ligands with any type of donor atoms are called coronands ("crown compounds"), while the term crown ether should be reserved for cyclic oligoethers exclusively containing oxygen as donor atom.

Download or read book Organic Nanoreactors written by Samahe Sadjadi and published by Academic Press. This book was released on 2016-03-28 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic Nanoreactors: From Molecular to Supramolecular Organic Compounds provides a unique overview of synthetic, porous organic compounds containing a cavity which can encapsulate one or more guest(s). Confined space within a nanoreactor can isolate the guest(s) from the bulk and effectively influence the reaction inside the nanoreactor. Naturally occurring enzymes are compelling catalysts for selective reactions as their three-dimensional structures build up clefts, caves, or niches in which the active site is located. Additionally, reactive sites carrying special functional groups allow only specific reagents to react in a particular way, to lead to specific enantiomers as products. Equipped with suitable functional groups, then, nanoreactors form a new class of biomimetic compounds, which have multiple important applications in the synthesis of nanomaterials, catalysis, enzyme immobilization, enzyme therapy, and more. This book addresses various synthetic, organic nanoreactors, updating the previous decade of research and examining recent advances in the topic for the first comprehensive overview of this exciting group of compounds, and their practical applications. Bringing in the Editor’s experience in both academic research and industrial applications, Organic Nanoreactors focuses on the properties and applications of well-known as well as little-examined nanoreactor compounds and materials and includes brief overviews of synthetic routes and characterization methods. Focuses on organic nanoreactor compounds for greater depth Covers the molecular, supramolecular, and macromolecular perspectives Compiles previous and current sources from this growing field in one unique reference Provides brief overviews of synthetic routes and characterization methods

Download or read book Chirality in Drug Design and Synthesis written by C. Brown and published by Academic Press. This book was released on 2013-10-22 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chirality in Drug Design and Synthesis is a collection of papers that discusses the property of asymmetry in the structural and synthetic chemistry of natural products, including the significance of chirality in medicinal chemistry. These papers examine the need for the preparation and study of pure enantiomers of chiral drug substances and their mechanism of interaction with enzymes and receptors. These papers also investigate the techniques in studying these interactions, as well as analyze the methods for their synthesis in enantiomerically pure form. One paper discusses the pharmacological and pharmacokinetic analyses made that point to the differences in the activity and disposition of enantiometric pairs. Another paper reviews the implications of the neglect of stereoselectivity at the different levels during the examination process of racemic drugs. Since no general guidelines exists for the development of drugs with chiral centers, one paper suggests a case-by-case approach in evaluating the safety and efficacy of drugs, particularly as regards how isomers differ in their effects. This collection is suitable for the pharmacologist, medicinal chemists, toxicologists, mechanistic chemists and synthetic organic chemists.

Download or read book Templated Organic Synthesis written by François Diederich and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Template-controlled reactions allow the synthesis of complex molecules which would hardly be achievable through classical methods. This handbook offers authoratative information on how noncovalent and covalent templates can be effectively applied to control reaction rates as well as regio- and stereoselectivity. From the concepts of template control such as molecular imprinting, self-replication, and reversible tether-directed remote functionalization, the reader is led to template-based ring-closing reactions, oligomerizations, and multiple functionalizations and their application in the synthesis of supramolecular scaffolds and natural products. The editors and authors (J. F. Stoddart, G. Wulf, D. Lynn, R. Breslow. F. Diederich, just to name a few ) , all internationally recognized experts in their area, succeeded in presenting the manifold aspects of template-controlled synthesis in a didactic way, making this methodology accessible to a broad readership of organic synthetic chemists. Well-selected, reliable key experimental protocols and an up-to-date reference list underline the practical approach of this valuable handbook. Being the first book of its kind, it will serve as a pacemaker and stimulate future research.
