Download or read book Protecting-Group-Free Organic Synthesis written by Rodney A. Fernandes and published by John Wiley & Sons. This book was released on 2018-08-20 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a comprehensive account of established protecting-group-free synthetic routes to molecules of medium to high complexity This book supports synthetic chemists in the design of strategies, which avoid or minimize the use of protecting groups so as to come closer to achieving an “ideal synthesis” and back the global need of practicing green chemistry. The only resource of its kind to focus entirely on protecting-group-free synthesis, it is edited by a leading practitioner in the field, and features enlightening contributions by top experts and researchers from across the globe. The introductory chapter includes a concise review of historical developments, and discusses the concepts, need for, and future prospects of protecting-group-free synthesis. Following this, the book presents information on protecting-group-free synthesis of complex natural products and analogues, heterocycles, drugs, and related pharmaceuticals. Later chapters discuss practicing protecting-group-free synthesis using carbohydrates and of glycosyl derivatives, glycol-polymers and glyco-conjugates. The book concludes with a chapter on latent functionality as a tactic toward formal protecting-group-free synthesis. A comprehensive account of established protecting-group-free (PGF) synthetic routes to molecules of medium to high complexity Benefits total synthesis, methodology development and drug synthesis researchers Supports synthetic chemists in the design of strategies, which avoid or minimize the use of protecting groups so as to come closer to achieving an “ideal synthesis” and support the global need of practicing green chemistry Covers a topic that is gaining importance because it renders syntheses more economical Protecting-Group-Free Organic Synthesis: Improving Economy and Efficiency is an important book for academic researchers in synthetic organic chemistry, green chemistry, medicinal and pharmaceutical chemistry, biochemistry, and drug discovery.

Download or read book Protective Groups in Organic Chemistry written by J. McOmie and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade there has been a great increase in the use of protective groups, especially in the synthesis of large and complex organic molecules. Perhaps the greatest activity has been in the peptide field where such triumphs as the total synthesis of insulin and of bovine ribonuclease (molecular weight 13,700) have been achieved. Correspondingly, more protective groups have been devised for the protection of amino and imino groups than for any other functional group. There are many reviews and books on the synthesis of pep tides but there has been no general survey of protective groups since my 1 own review in 1963. At that time the five main methods for the removal of protective groups involved acid or base hydroly sis, reduction, oxidation, or thermal elimination reactions. Recent advances include the use of photo-sensitive and metal ion sensitive protective groups, and the attachment of functional groups to reactive polymers as a method of protec tion during the solid-phase synthesis of peptides and poly nucleotides. Another interesting development is the design and use of protective groups with a built-in 'safety-catch', which can be 'released' by a specific chemical reaction, so that an otherwise stable bond is made labile at the appropriate moment thereby allowing the protective group to be removed under very 2 mild conditions. My own interest in protective groups dates from 1944 when, as a student, I gave two lectures on the subject and produced an 11 page review including 70 references.

Download or read book Protecting Groups in Organic Synthesis written by James R. Hanson and published by Wiley-Blackwell. This book was released on 1999-11-15 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides, at postgraduate student level, an accessible introduction to a topic of central importance in organic synthesis. It covers the main functional groups requiring protection in organic synthesis, explaining why a particular protecting agent works and how an agent should be chosen. Emphasis is placed on what a protecting group is doing chemically to the structure that it is protecting. Attention is given to removal of the protecting group. This is a clear and thoughtful book, which concentrates on explaining the chemistry. It also provides a convenient point of entry to the primary literature.

Download or read book Elements of Synthesis Planning written by R. W. Hoffmann and published by Springer Science & Business Media. This book was released on 2009-01-07 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesis is at the core of organic chemistry. In order for compounds to be studied—be it as drugs, materials, or because of their physical properties— they have to be prepared, often in multistep synthetic sequences. Thus, the target compound is at the outset of synthesis planning. Synthesis involves creating the target compound from smaller, readily available building blocks. Immediately, questions arise: From which bui- ing blocks? In which sequence? By which reactions? Nature creates many highly complex “natural products” via reaction cascades, in which an asso- ment of starting compounds present within the cell is transformed by speci c (for each target structure) combinations of modular enzymes in speci c - quences into the target compounds [1, 2]. To mimic this ef ciency is the dream of an ideal synthesis [2]. However, we are at present so far from - alising such a “one-pot” operation that actual synthesis has to be achieved via a sequence of individual discrete steps. Thus, we are left with the task of planning each synthesis individually in an optimal fashion. Synthesis planning must be conducted with regard for certain speci - tions, some of which are due to the structure of the target molecule, and some of which relate to external parameters such as costs, environmental compatibility, or novelty. We will not consider these external aspects in this context. Planning of a synthesis is based on a pool of information regarding chemical reactions that can be executed reliably and in high chemical yield.

This book was released on 2019-04-29 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique overview of the most important protecting group strategies in carbohydrate chemistry Protecting Groups: Strategies and Applications in Carbohydrate Chemistry provides a detailed account of key strategies and methodologies for the protection of carbohydrates. Divided into two parts, the first focuses on groups that are used best to protect a specific position on a carbohydrate. In the second part, specific carbohydrate residues or compounds are discussed in the context of a specific protecting group strategy used to reach the desired regioisomer. This important book: -Features chapters on protecting groups at the primary and secondary positions of carbohydrates -Describes protecting group strategies towards sialic acid derivatives, glycofuranoses, sulfated glycosaminoglycans, and cyclodextrins -Provides information on automated glycan assembly -Includes a chapter on the industrial scale synthesis of heparin analogs Written by a team of leaders in the field, Protecting Groups: Strategies and Applications in Carbohydrate Chemistry is an indispensable guide for academics and industrial researchers interested in carbohydrate and natural product synthesis, pharmaceutical chemistry, and biochemistry.
