Book Description
Provides a unique overview of efficient synthetic routes to one of the most important compound classes in organic and pharmaceutical chemistry! Amines are among the most important compounds in organic chemistry due to their wide occurrence in natural products, drugs, crop protection compounds, and advanced materials. For example, the majority of drugs are amines or contain functional groups derived from amines. Powerful and efficient methods for the introduction of the amino group are therefore of great importance to synthetic chemists in academia and industry. Methodologies in Amine Synthesis: Challenges and Applications presents powerful and state-of-the-art methods for the efficient preparation of amines. It summarizes recent advances in the electrophilic amination reaction, hydroamination, C?H amination as well as newly developed photocatalytic approaches. It further describes organocatalytic and enzymatic routes to the generation of amines under mild and environmentally friendly conditions. In addition, it highlights the relevance of the amino function in bioactive molecules, drugs, and in the engineering of smart materials. Finally, the application of palladium-catalyzed aromatic amination in industrial context is critically discussed. Only up-to-date and comprehensive book on the preparation of amines ? one of the most frequently occurring compound classes found in natural products, bioactive molecules, and advanced materials. Presents efficient and useful synthetic methods, highlights opportunities / challenges as well as applications in pharmaceutical chemistry and materials science. Chapters are compiled by well-known experts in the field. One of them edited the previous books Modern Amination Methods (2001) and Amino Group Chemistry (2007). The book Methodologies in Amine Synthesis: Challenges and Applications is a musthave for chemists in academia and industry working in the field of organic synthesis and catalysis, natural product chemistry, drug synthesis and pharmaceutical chemistry, as well as materials science.

Biocatalysis for Practitioners
Author: Gonzalo de Gonzalo
Publisher: John Wiley & Sons
ISBN: 352734683X
Category : Science
Languages : en
Pages : 54
Book Description
This reference book originates from the interdisciplinary research cooperation between academia and industry. In three distinct parts, latest results from basic research on stable enzymes are explained and brought into context with possible industrial applications. Downstream processing technology as well as biocatalytic and biotechnological production processes from global players display the enormous potential of biocatalysts. Application of "extreme" reaction conditions (i.e. unconventional, such as high temperature, pressure, and pH value) - biocatalysts are normally used within a well defined process window - leads to novel synthetic effects. Both novel enzyme systems and the synthetic routes in which they can be applied are made accessible to the reader. In addition, the complementary innovative process technology under unconventional conditions is highlighted by latest examples from biotech industry.

Pages : 391
Book Description
Biocatalysts are increasingly used by chemists engaged in fine chemical synthesis within both industry and academia. Today, there exists a huge choice of high-tech enzymes and whole cell biocatalysts, which add enormously to the repertoire of synthetic possibilities. Practical Methods for Biocatalysis and Biotransformations 2 is a "how-to" guide that focuses on the practical applications of enzymes and strains of microorganisms that are readily obtained or derived from culture collections. The sources of starting materials and reagents, hints, tips and safety advice (where appropriate) are given to ensure, as far as possible, that the procedures are reproducible. Comparisons to alternative methodology are given and relevant references to the primary literature are cited. This second volume – which can be used on its own or in combination with the first volume - concentrates on new applications and new enzyme families reported since the first volume. Contents include: introduction to recent developments and future needs in biocatalysts and synthetic biology in industry reductive amination enoate reductases for reduction of electron deficient alkenes industrial carbonyl reduction regio- and stereo- selective hydroxylation oxidation of alcohols selective oxidation industrial hydrolases and related enzymes transferases for alkylation, glycosylation and phosphorylation C-C bond formation and decarboxylation halogenation/dehalogenation/heteroatom oxidation tandem and sequential multi-enzymatic syntheses Practical Methods for Biocatalysis and Biotransformations 2 is an essential collection of biocatalytic methods for chemical synthesis which will find a place on the bookshelves of synthetic organic chemists, pharmaceutical chemists, and process R&D chemists in industry and academia.
