| organic chemistry protecting groups: Protective Groups in Organic Chemistry J. McOmie, 2012-12-06 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. |

| organic chemistry protecting groups: Protecting Group Chemistry Jeremy Robertson, 2000 Protecting Group Chemistry provides an overview of the general methods that are used to block the reactivity of - i.e. protect - specific functional grops thus allowing others, present within the same molecule, to be manipulated unambiguously. An introductory chapter outlines protecting group strategy, relevant aspects of functional group reactivity, temporary protection, and introduces the concept of protecting group devices as an aid to unifying the wide range of available methods. Therest of the book is divided on the basis of broad classes of the experimental conditions that lead to cleavage of each protecting group (acid/electrophile, base/nucleophile, oxidising or reducing agent). The treatment differs from traditional texts in that it places the emphasis on making a connection between the fundamental mechanisms of organic chemsitry - ionisation, substitution, addition, elimination, oxidation and reduction, etc. - and how a particular protecting group can best be selected in a given situation. |

| organic chemistry protecting groups: Elements of Synthesis Planning R. W. Hoffmann, 2009-01-07 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. |
| organic chemistry protecting groups: Handbook of Reagents for Organic Synthesis Tomislav Rovis, 2016-10-20 Spurred by the desire to make chemistry a sustainable and greener technology, the field of organocatalysis has grown to become one of the most important areas in synthetic organic chemistry. Organic catalysts can often replace potentially toxic metal catalysts and allow reactions to proceed under mild reaction conditions, thereby saving energy costs and rendering chemical processes inherently safer. More importantly perhaps, organocatalysis offers a complementary reactivity in many instances leading to increased versatility.This Handbook describes 126 key reagents for organocatalytic reactions and will be especially useful for professionals in the area of sustainable chemistry, medicinal research, as well as synthetic organic chemists working in academia and the pharmaceutical industry. All the information compiled in this volume is also available in electronic format on Wiley Online Library. The 126 reagents represented here are but a small fraction of the ca. 5,000 reagents available in the electronic Encyclopedia of Reagents for Organic Synthesis (e-EROS). e-EROS offers various search interfaces to locate reagents of interest, including chemical structure, substructure and reactions search modes. e-EROS is updated regularly with new and updated entries. |

| organic chemistry protecting groups: Heterogeneous Catalysis in Organic Chemistry Gerard V. Smith, Ferenc Notheisz, 1999-06-30 The features of this book which will be of special interest to academic organic chemists are the introduction (Chapter 1), which presents a short course on the concepts and language of heterogeneous catalysis, covers organic reaction mechanisms of hydrogenation (Chapter 2), hydrogenolysis (Chapter 4), and oxidation (Chapter 6), a presents problems and solutions specific for running heterogeneous catalytic organic reactions in solution. These materials can supplement advanced chemistry courses. Most synthetic organic chemists use a variety of protecting groups which they attach to functional groups (reactive groups of atoms) while some reaction is being conducted on another part of the molecule. These protecting groups prevent reactions of the functional groups during other reactions and are removed later by a heterogeneous catalytic method called hydrogenolysis. One unique feature of this book, not found in other books on catalysis, is an exhaustive chapter (Chapter 4) on hydrogenolysis, which is dredged from the recent synthetic literature published by modern organic chemists. Academic organic chemists should find this chapter extremely useful and may wish to adopt the book as a supplement for advanced organic chemistry courses designed for seniors and for graduate students. It will also be useful for professors and their research groups engaged in synthetic organic chemistry. Many academic organic chemists are not aware of recent advances in heterogeneous enantioselective catalysis (Chapter 3) or in selective low temperature, liquid phase heterogeneous catalytic oxidations by hydrogen peroxide (Chapter 6). These specialty topics are timely and may be new to academic organic chemists and can be used to supplement their advanced courses. Several features of this book will also be of special interest to industrial chemists who are unfamiliar with heterogeneous catalysis. Many good organic chemists are hire by industry. They synthesize a new compound using standard organic synthetic techniques but are informed by their supervisor that they must convert some of their synthetic steps into heterogeneous catalytic steps. They may not have been exposed to heterogeneous catalysis and have few places to turn. This book offers them a crash course in heterogeneous catalysis as well as many examples of reactions and conditions with which they can start their search. Those industrial organic chemists already familiar with heterogeneous catalysis will find this book useful as a reference to many examples in the recent literature. They will find recent surface science discoveries correlated with heterogeneous catalysis or organic reactions and mechanistic suggestions designed to stimulate innovative nontraditional thinking about organic reactions on surfaces. - Written by organic chemists for organic chemists - Introduces heterogeneous catalysis concepts and language - Presents a comprehensive compilation of protecting group removal procedures - Covers liquid-phase hydrogenations, hydrogenolysis, and oxidations - Addresses heterogeneous methods for producing pure enantiomers of chiral products - Examines the emerging field of heterogenized homogeneous catalysts - Mixes practical applications with mechanistic interpretations |
