In recent years the intense activities of enantioselective synthesis have been reflected in the burgeoning and ingenious applications of such natural substances as carbohydrates, α-amino acids and terpenes. A comprehensive summary of terpene-based synthesis is offered, focusing on synthetic efforts using transformed chiral synthons. The author provides analysis of synthetic strategies and discusses the intricacies of reaction courses. Along with the number and variety of natural products derived from chiral terpenes, numerous flow-charts aid in clearly delineating synthetic pathways.
Heterocyclic chemistry constitutes the largest branch of chemistry, covering almost two-thirds of literature in the field. In addition, around 90% of naturally-occurring molecules have heterocycles as their core structure. Therefore, as a central part of organic chemistry, the discovery of new methodologies in synthesizing heterocyclic compounds is essential to their continued application and development. Transition metal catalysts offer a low cost and often low toxicity pathway for heterocycles synthesis, while the use of noble metals represents an alternative form of experimentation which is discussed in the book.Noble Metals, Noble Value provides the first comprehensive analysis of the applications of the noble metals of ruthenium (Ru), rhodium (Rh) and palladium (Pd) catalysts in heterocycles synthesis. Pairs of chapters are dedicated to summarizing each of the metals when applied to either five- or six-membered heterocyclic syntheses. An introduction to the importance of heterocycles and possible procedures for the preparation of heterocyclic compounds is also given.With up to date research and findings, this review is excellently suited to academics and professionals in the field of chemistry, with a particular focus on the specialities of biological, catalytic and organic chemistry.
The field of asymmetric catalysis is currently one of the hottest areas in chemistry. This unique book focuses on the mechanism of enantioselectivity in asymmetric catalysis, rather than asymmetric catalysis from the synthetic view. It describes reliable, experimentally and computationally supported mechanisms, and discusses the danger of so-called "plausible" or "accepted" mechanisms leading to wrong conclusions. It draws parallels to enzymatic catalysis in biochemistry, and examines in detail the physico-chemical aspects of enantioselective catalysis.
Sodium Dithionite, Rongalite and Thiurea Oxides provides an in depth overview of historical and newly developed fields of application for important sulfur-containing reductants. It begins with an introduction into the structure and general properties of sodium dithionite, sodium hydroxymethanesulfinate (rongalite) and thiourea oxides. Following this there is analysis of their stability in different types of solutions, and reactions with both organic and inorganic compounds. Finally, there is description of the application of the reductants in industry, using examples of the textile, printing and paper industries, as well as in polymerization processes.Despite widespread practical application, the mechanism behind these compounds is not fully understood, due to their unusual structure and complex decomposition within solutions. This comprehensive review presents up-to-date findings to both academics and industrial chemists, aiming to increase knowledge and provide both fundamental and technical data dedicated to these relatively simple chemicals which have wide practical applications.
This revised edition has been updated to meet the minimum requirements of the new Singapore GCE A level syllabus that would be implemented in the year 2016.

Organic Reaction Mechanisms shows readers how to interpret the experimental data obtained from an organic reaction, and specifically how an organic reaction mechanism can be considered or rejected based on the analysis of the experimental evidence. Whilst examining a series of selected examples of mechanisms, the text focuses on real cases and discusses them in detail. The examples are arranged to elucidate key aspects of organic reaction mechanisms. The authors employ all the types of information that the authors of the original work considered useful and necessary, including spectroscopic data, kinetic and thermodynamic data, isotopic labelling and organic reactivity. The book makes an excellent primer for advanced undergraduates in chemistry who are preparing for exams and is also useful for graduate students and instructors.
During the last 30 years, knowledge of the essential role that pyrrole structures play in the chemistry of living organisms, drug design, and the development of advanced materials has increased. Correspondingly, research on the diverse issues of synthetic, theoretical, and applied chemistry has snowballed. Devoted to the latest achievements of this field, Chemistry of Pyrroles covers the discovery and development of a novel, facile, and highly effective method for the construction of the pyrrole ring from ketones (ketoximes) and acetylene in superbase catalytic systems (Trofimov reaction). It provides cutting-edge details on the preparation of valuable but previously inaccessible pyrrole compounds. It includes approximately 1,000 structures of novel pyrrole compounds, their yields, and physical-chemical characteristics. The authors analyze conditions of typical syntheses, limitations of their applicability, and possibility of vinyl chloride or dichloroethane application instead of acetylene. They examine chemical engineering aspects of the first synthesis of tetrahydroindole and indole from commercially available oxime of cyclohexanone and acetylene. In addition, the book discusses new facets of pyrroles and N-vinyl pyrroles reactivity in the reactions with the participation of both the pyrrole ring and N-vinyl groups. The book provides condensed, clear-cut information on novel syntheses of substituted pyrroles as key structural units of living matter (chlorophyll and hemoglobin), pharmaceuticals, and monomers for optoelectronic materials. It includes tables that provide references to original works, forming a guide to a variety of the reactions and synthesized compounds discussed. With coverage of the broad range of pyrrole chemistry and methods for their synthesis, it provides both a theoretical and an experimental basis for drug design.
-Conjugated molecules with an even number of -electrons usually have a closed-shell ground state. However, recent studies have demonstrated that a certain type of molecules could show open-shell singlet ground state and display diradical-like (diradicaloid) behavior. Their electronic structure can be understood in terms of the "diradical character" and "aromaticity" concepts. They display very different electronic properties from traditional closed-shell -conjugated molecules and could be used as next-generation molecular materials. This book provides a comprehensive review on the chemistry, physics, and material applications of open-shell singlet diradicaloids. Particularly, it elaborates the fundamental structure-diradical character-electronic property relationships both theoretically and experimentally. The book has been written by leading scientists in the field from Japan, Germany, Spain, Italy, China, and Singapore.

The chapters presented in Secondary Metabolism in Model Systems are
a microcosm of what the recent completion, or near completion, of
various genome projects are enabling biochemists to understand not
only about control and regulation of secondary metabolism, and how
various pathways relate to each other, but also about its relation
to primary metabolism. A major paradigm shift is occurring in the
way researchers need to view "secondary" metabolism in the
future.It is also clear that model systems, such as the ones
discussed in the symposium, are providing new information and
insight almost faster than researchers can process it . An excellent series volume covering the advances in
understanding of gene functions, a high profile area of research
due to recent genome projects

This book includes experiments that cover a range of green chemistry principles, particularly in the field of organic chemistry. Green chemistry, as we know it today, revolves around a set of twelve principles that were outlined 1998. The experiments presented in this text utilize many of the 12 Principles of Green Chemistry. Each chapter presents an experiment that utilizes at least one, if not more, of these principles. This book is targeted for any professor who would like to introduce green or "greener" laboratory experiments for their students in any chemistry course regardless of level. The book is designed to introduce students to the ideas, principles, and benefits of green chemistry and inspire educators to adopt more green chemistry principles in their course.
This monograph describes the behavior of molecules confined to small spaces. The small spaces are created by the self-assembly of modules into hollow capsular structures through hydrogen bonding; capsules assembled by metal/ligand binding or other forces are not included. Topics discussed include how assembly of capsules occurs, how molecules get in and out of the capsules, new spatial arrangements (stereochemistry) created in the capsules, and the altered shapes, interactions and reactivities of molecules held inside the small spaces. The descriptions emphasize molecular recognition phenomena and the perspective is that of physical organic chemistry.The book is the first monograph to treat reversible molecular encapsulation. More than 20 university and institute groups worldwide engage in this research, which represents the leading edge of activity in molecular recognition and the physical organic chemistry of confined molecules.

An extensive update of the classic reference on organic reactions
in water
This innovative book presents an original account of the principles of conformational theory. It has a strong focus on computational methodologies for conformational space exploration. By revisiting basic conformational conventions, considering experimental results which are often misinterpreted by organic chemists, and qualitatively analyzing the potential energy surface, the book helps non-experts to understand molecular flexibility at the level required in contemporary research.The book shows synthetic organic chemists how to perform successful conformational studies using widespread calculation packages ('click computational chemistry') instead of being misguided by textbook-based conformational analysis. The monograph actually offers to synthetic chemists a new research tool that can significantly upgrade their ability to predict, or at least explain, regioselectivity and stereoselectivity in their own reactions. |
