Total Steroid Synthesis

Total Steroid Synthesis PDF Author: A. A. Akhrem
Publisher: Springer Science & Business Media
ISBN: 1475705875
Category : Science
Languages : en
Pages : 368

Book Description
Since the appearance of the Russian edition of this monograph (1967), the main tendencies of the development of total synfuesis have not changed. The accelerated accumulation of experimental material is continuing, mainly in the form of the improvement of already-existing synthesis schemes. The main new advance is the development of asymmetric syn theses with intermediates that have made it possible to avoid the main dis advantage of total synthesis - the formation of racemic final compounds. The most important work that has appeared since the appearance of the Russian edition is given in an Appendix to the book. Apart from this, only a very slight rearrangement of the material and of some of the schemes has been carried out for the American edition. A. A. Akhrem Yu. A. Titov Moscow, July 1968 v Preface to the Russian Edition Steroids are one of the most interesting and most widely distributed and, at the same time, one of the most structurally complex groups of natural compounds. In spite of this, the great theoretical and practical importance of steroids for biology and medicine has led to very intensive scientific research work on their synthesis. The numerous methods for obtaining steroids developed at the present time can be divided into four main groups: isolation from natural sources, microbiological synthesis, partial synthesis from natural raw material already containing the steroid skeleton, and, finally, total chemical synthesis from precursors of com paratively simple structure.

The Chemistry of Dienes and Polyenes, Volume 1

The Chemistry of Dienes and Polyenes, Volume 1 PDF Author: Zvi Rappoport
Publisher: Wiley-Blackwell
ISBN:
Category : Science
Languages : en
Pages : 1090

Book Description
Dienes and polyenes are an extremely important group of chemicals in the investigation of different types of syntheses. Dienes and Polyenes are found in a large number of natural and man-made products including such natural products as terpenes, cholesterol, Vitamin A, and many essential oils, as well as many polymers and rubber products. In recent years the organometallic complexes of these compounds have been found to play an important role in synthesis. This volume is an invaluable reference source for researchers in academia and industry in organic and natural product chemistry and materials science. An extensive work covering all aspects of the synthetic analytical, biochemical, physical, and environmental aspects of these important molecules.

1,4-Cycloaddition Reaction: The Diels-Alder Reaction in Heterocyclic Syntheses

1,4-Cycloaddition Reaction: The Diels-Alder Reaction in Heterocyclic Syntheses PDF Author: Jan Hamer
Publisher: Elsevier
ISBN: 0323163114
Category : Science
Languages : en
Pages : 513

Book Description
Organic Chemistry, Volume 8: 1,4-Cycloaddition Reactions: The Diels-Alder Reaction in Heterocyclic Syntheses describes 1,4-cycloaddition reactions leading to the formation of five- or six-membered heterocyclic compounds. Divided into 13 chapters, this book starts with an overview of various 1,4-cycloaddition reaction equations in the presence of at least one atom other than carbon. The following chapters describe the reaction mechanisms of five- or six-membered ring formed upon reaction with a dienophile, which contains an atom other than carbon. Considerable chapters are devoted to compounds used as dienophiles, including trivalent phosphorus, cyanogens and cyanogens-like compounds, imino, azo, carbonyl, thiocarbonyl, and diene compounds, as well as oxygen. Other chapters highlight some 1,4-cycloaddition reactions taking place through free radical intermediates. This book is of value to organic and research chemists, as well as undergraduate and graduate organic chemistry students.

The Total Synthesis of Natural Products, Volume 8

The Total Synthesis of Natural Products, Volume 8 PDF Author: John ApSimon
Publisher: John Wiley & Sons
ISBN: 9780471545071
Category : Science
Languages : en
Pages : 726

Book Description
Organic chemistry's innovative breadth is especially noteworthy in the area of natural products synthesis. Since the early 1970s, this landmark chemical reference has been documenting the newest and most important of these, in a readily understood format, that clearly traces each of their synthetic routes. Volume Eight, the latest in the series, contains a long-awaited look at the synthesis of tri- and tetracyclic diterpenes, along with the synthesis of naturally occurring quinones. Recent interest in the biologically important polysaccharides has led to a detailed consideration of that compound class. Finally, this new volume contains a look at the strategies and methods specific to natural products containing the spiroketal functional group. The Total Synthesis of Natural Products, Volume Eight, continues the meticulous work of the series, providing chemists with an entirely up-to-date and convenient guide to the critical new syntheses essential to organic chemistry's continuing evolution.

Comprehensive Organic Functional Group Transformations

Comprehensive Organic Functional Group Transformations PDF Author: Alan R. Katritzky
Publisher: Elsevier
ISBN: 9780080423227
Category : Mathematics
Languages : en
Pages : 1452

Book Description
This Volume covers the formation of carbon-carbon single-, double- and triple bonds by substitution and addition reactions as well as by various rearrangements. The formation of carbon-carbon multiple bonds by elimination and condensation procedures is fully documented. In addition the synthesis of carbon-hydrogen bonds principally by substitution and addition reactions is featured as is the preparation of a wide variety of carbon-centred anions, cations and radicals.

Sterilisation of Biomaterials and Medical Devices

Sterilisation of Biomaterials and Medical Devices PDF Author: Sophie Lerouge
Publisher: Elsevier
ISBN: 0857096265
Category : Medical
Languages : en
Pages : 347

Book Description
The effective sterilisation of any material or device to be implanted in or used in close contact with the human body is essential for the elimination of harmful agents such as bacteria. Sterilisation of biomaterials and medical devices reviews established and commonly used technologies alongside new and emerging processes.Following an introduction to the key concepts and challenges involved in sterilisation, the sterilisation of biomaterials and medical devices using steam and dry heat, ionising radiation and ethylene oxide is reviewed. A range of non-traditional sterilisation techniques, such as hydrogen peroxide gas plasma, ozone and steam formaldehyde, is then discussed together with research in sterilisation and decontamination of surfaces by plasma discharges. Sterilisation techniques for polymers, drug-device products and tissue allografts are then reviewed, together with antimicrobial coatings for 'self-sterilisation' and the challenge presented by prions and endotoxins in the sterilisation of reusable medical devices. The book concludes with a discussion of future trends in the sterilisation of biomaterials and medical devices.With its distinguished editors and expert team of international contributors, Sterilisation of biomaterials and medical devices is an essential reference for all materials scientists, engineers and researchers within the medical devices industry. It also provides a thorough overview for academics and clinicians working in this area. - Reviews established and commonly used technologies alongside new and emerging processes - Introduces and reviews the key concepts and challenges involved in sterilisation - Discusses future trends in the sterilisation of biomaterials and medical devices
