Download or read book Phenolic Oxidative Coupling written by Wesley Kwan Mung Chong and published by . This book was released on 1983 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various hypervalent iodine compounds were evaluated as reagents for intramolecular phenolic oxidative coupling. It was found that phenyliodine(III) bis(trifluoroacetate) was effective for the coupling of the monophenolic substrate 13a to 14a under neutral conditions. Vanadium oxytrifluoride and hypervalent iodine compounds were compared as oxidants for the conversion of 32 to 33. In an approach directed at a synthesis of pretazettine (17), phenacylamine 57 was elaborated in two steps to oxazole 50. However, this did not undergo catalytic hydrogenation to the desired oxazolidine 47. Oxazoline 60 proved to be too labile to be isolated upon dehydration of 65, which was prepared from di-octopamine (64) and the acid chloride of piperonylic acid (58). Finally, 64 and piperonal (69) were condensed and treated with ethyl chloroformate to provide trans-2,5-diaryloxazolidine 73. However, the latter was hydrolyzed under coupling conditions. Alternatively, when octopamine and piperonal were condensed and hydrogenated, amine 74 was obtained, which was in turn reacted with 1,1'-carbonyldiimidazole (75) to furnish the 2-oxazolidinone 76. Exposure of 76 to vanadium oxytrifluoride led to 78, which apparently arose from an undesired, spontaneous rear- rangement of the coupling product 77. Attempts to synthesize ether 79 starting with synephrine (81), 2-nitrostyrenes 86, and 4-hydroxymandelates 90 are described. The oxazolidine 97 was prepared from the condensation of synephrine 81 and treated with methyl chioroformate in the presence of methanol to afford acetal 100 in 71% yield. Phenyliodine(III) bis- (trifluoroacetate) was employed to couple 100 to 101 in 5 to 7% yield. Hydrolysis of the urethane moiety of 101 with potassium hydroxide in ethylene glycol gave the amine 105, which underwent a spontaneous cyclization to 107. Formation of the unnatural, cis B-D ring fusion stereochemistry in this ring closure was ascertained by nuclear magnetic resonance spectroscopy.

Available in PDF, EPUB and Kindle. Book excerpt: A practical introduction to orbital interaction theory and its applications in modern organic chemistry Orbital interaction theory is a conceptual construct that lies at the very heart of modern organic chemistry. Comprising a comprehensive set of principles for explaining chemical reactivity, orbital interaction theory originates in a rigorous theory of electronic structure that also provides the basis for the powerful computational models and techniques with which chemists seek to describe and exploit the structures and thermodynamic and kinetic stabilities of molecules. Orbital Interaction Theory of Organic Chemistry, Second Edition introduces students to the fascinating world of organic chemistry at the mechanistic level with a thoroughly self-contained, well-integrated exposition of orbital interaction theory and its applications in modern organic chemistry. Professor Rauk reviews the concepts of symmetry and orbital theory, and explains reactivity in common functional groups and reactive intermediates in terms of orbital interaction theory. Aided by numerous examples and worked problems, he guides readers through basic chemistry concepts, such as acid and base strength, nucleophilicity, electrophilicity, and thermal stability (in terms of orbital interactions), and describes various computational models for describing those interactions. Updated and expanded, this latest edition of Orbital Interaction Theory of Organic Chemistry includes a completely new chapter on organometallics, increased coverage of density functional theory, many new application examples, and worked problems. The text is complemented by an interactive computer program that displays orbitals graphically and is available through a link to a Web site. Orbital Interaction Theory of Organic Chemistry, Second Edition is an excellent text for advanced-level undergraduate and graduate students in organic chemistry. It is also a valuable working resource for professional chemists seeking guidance on interpreting the quantitative data produced by modern computational chemists.

Available in PDF, EPUB and Kindle. Book excerpt: “Applied Cross-Coupling Reactions” provides students and teachers of advanced organic chemistry with an overview of the history, mechanisms and applications of cross-coupling reactions. Since the discovery of the transition-metal-catalyzed cross-coupling reactions in 1972, numerous synthetic uses and industrial applications have been developed. The mechanistic studies of the cross-coupling reactions have disclosed that three fundamental reactions: oxidative addition, transmetalation, and reductive elimination, are involved in a catalytic cycle. Cross-coupling reactions have allowed us to produce a variety of compounds for industrial purposes, such as natural products, pharmaceuticals, liquid crystals and conjugate polymers for use in electronic devices. Indeed, the Nobel Prize for Chemistry in 2010 was awarded for work on cross-coupling reactions. In this book, the recent trends in cross-coupling reactions are also introduced from the point of view of synthesis design and catalytic activities of transition-metal catalysts.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of new strategies to access pyridinium salts are highly sought out due to their advantageous structures, which have diverse applications across materials science, biological processes, and organic synthesis. As synthetic intermediates, these scaffolds can be used as precursors to valuable piperidine derivatives and have recently emerged as important cross coupling handles for metal-catalyzed processes. Unfortunately, current methods to access pyridinium salts are limited; they require harsh conditions, rely on the presence of an amine functional handle, and are not amenable to diverse structural variation. In Chapter 1, a summary of various syntheses and the reactivity of pyridinium salts is provided. This dissertation provides new strategies to access pyridinium salts. The first method is via aminolactonization of alkenoic acids, resulting in 1° pyridinium salts (Chapter 2). The second method is a regioselective synthesis of 3-aminopiperidine salts via diamination of olefins (Chapter 3). Both methods are promoted by nitrogen-ligated hypervalent iodine reagents (N-HVIs). These novel class of reagents serve as "heterocyclic group transfer reagents," incorporating diverse pyridinium salts under mild conditions and in excellent yields. Heterocyclic Group Transfer reactions have resulted in new classes of pyridinium salts that can be further functionalized via simple known methods to access diverse piperidine motifs, providing an innovative approach to substitution patterns that were previously challenging to synthesize. These strategies have also enabled pyridinium salts to be viewed as a synthetic platform for diversity-oriented amine synthesis. Chapter 4 will elaborate on the synthesis of different classes of 3-aminopiperidine motifs using hypervalent iodine reagents; these motifs have been previously synthesized using transition metal catalysis.
