Book Description
Metallocene is a well known sandwich complex with two cyclopentadienyl ligands such as ferrocene. Recently, such metallocene compounds have been found to be very characteristic and they have become very important, not only in the area of organic synthesis, but also in polymerization in industry. Metal complexes with one cyclopentadienyl ligand have also become popular as half sandwich complexes. The number of researchers in the field of metallocenes has increased rapidly. However, the origin of the characteristic reactivity of metallocenes is not fully understood. In this volume, the chemistry of metal complexes with at least one cyclopentadienyl ligand is comprehensively covered by leading experts. Reactions discussed here are (i) natural product synthesis, (ii) catalytic asymmetric synthesis, (iii) cyclization reactions, (iv)catalytic reactions, (iv) polymerization reactions and (v) carbon-carbon bond cleavage reactions. The reader will have access to useful information about the current state of metallocene chemistry.

Book Description
This book systematically reviews recent advances in the synthetic methods and applications of helicenes. The first part of this book introduces the nomenclature and structural features of helicenes. The second part reviews several classic and useful methods as well as recently-developed approaches for the preparation and functionalization of helicenes, including photocyclization and Diels-Alder reactions, which are two important breakthroughs in the syntheses of helicenes. In the last part, the applications of helicenes in asymmetric syntheses, molecular machines, molecular recognition, self-assembly and other fields are discussed. This book provides a useful reference source for researchers and graduate students working not only in the area of helicene chemistry, but also in other research areas including materials science, supramolecular chemistry, coordination chemistry, and physical organic chemistry. Chuan-Feng Chen is a Professor at the Institute of Chemistry, Chinese Academy of Sciences, China.

Book Description
Derived from the renowned, Encyclopedia of Reagents for Organic Synthesis (EROS), the related editors have created a new handbook which focuses on chiral reagents used in asymmetric synthesis and is designed for the chemist at the bench. This new handbook follows the same format as the Encyclopedia, including an introduction and an alphabetical arrangement of the reagents. As chiral reagents are the key for the successful asymmetric synthesis, choosing the right reagents is essential, in this handy reference the editors give details on how to prepare, store and use the reagents as well as providing key reactions to demonstrate where reagents have been successfully used. Comprehensive information on 226 reagents Covers 64 reagents which were not included in EROS All information in one easy to use volume – at an affordable price All reagents included will be added to e-EROS – please visit the site where you can gain access to over 50,000 reactions and 3,800 of the most frequently consulted reagents.

Book Description
The world is chiral. Most of the molecules in it are chiral, and asymmetric synthesis is an important means by which enantiopure chiral molecules may be obtained for study and sale. Using examples from the literature of asymmetric synthesis, this book presents a detailed analysis of the factors that govern stereoselectivity in organic reactions. After an explanation of the basic physical-organic principles governing stereoselective reactions, the authors provide a detailed, annotated glossary of stereochemical terms. A chapter on "Practical Aspects of Asymmetric Synthesis" provides a critical overview of the most common methods for the preparation of enantiomerically pure compounds, techniques for analysis of stereoisomers using chromatographic, spectroscopic, and chiroptical methods. The authors then present an overview of the most important methods in contemporary asymmetric synthesis organized by reaction type. Thus, there are four chapters on carbon-carbon bond forming reactions, one chapter on reductions, and one on oxidations (carbon-oxygen and carbon-nitrogen bond forming reactions). This organization allows the reader to compare the leading methods for asymmetric synthesis in an appropriate context. A highlight of the book is the presentation and discussion of transition states at the current level of understanding, for important reaction types. In addition, extensive tables of examples are used to give the reader an appreciation for the scope of each reaction. Finally, leading references are provided to natural product synthesis that has been accomplished using a given reaction as a key step. - Authoritative glossary to aid understanding of stereochemical terminology - Explanations of the key factors influencing stereoselectivity with numerous examples, organized by reaction type - A handy reference guide to the literature of asymmetric synthesis for practitioners in the field
