Available in PDF, EPUB and Kindle. Book excerpt: Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.

Book Synopsis Discovery and Development of Novel Dirhodium Catalysts for Selective Intermolecular Allylic C-H Amination by : Kerry Nicole Betz

This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-catalyzed C--H functionalization has had an immense impact on streamlining synthesis by enabling previously inaccessible synthetic disconnections in organic synthesis and late-stage diversification of complex molecules. Dirhodium tetracarboxylate catalysts represent the state-of-the-art for intermolecular C(sp3)--H amination, but struggle to functionalize allylic sites due to the competitive reactivity of alkenes. Further advances in dirhodium-mediated C--H amination will require developing catalysts with enhanced stability and different ligand architectures to control selectivity in reactions with substrates bearing reactive functional groups and numerous C--H bonds. However, carboxylate ligands are inherently limited in their electronic, steric, and geometric tunability, which has severely hampered efforts to expand the scope of dirhodium-catalyzed C--H amination. To move beyond dirhodium tetracarboxylate catalysts, we developed a new, modular family of bridging ligands based on 2-pyridones. This work has advanced by capitalizing on a unique combination of computing tools, including molecular dynamics, transition state analysis, and statistical modeling, in a rationally connected feedback loop. These novel dirhodium catalysts mediate intermolecular allylic C−H amination with unprecedented selectivity. The most effective catalyst, Rh2(btz)3(O2CtBu), features one carboxylate and three substituted 2-pyridone ligands that create a spatially complex, conformationally dynamic reactive site. In addition to mediating high yielding amination reactions, these catalysts challenge the paradigm that rigid, well-defined ligand frameworks are optimal for controlling reaction outcomes. Our results demonstrate the versatility of 2-pyridone-derived ligands for optimizing catalyst performance. In addition, this work represents the first successful divergence from dirhodium tetracarboxylate complexes for catalyzing intermolecular C--H amination reactions. More broadly, our design blueprint showcases how data science and computational techniques can be implemented synergistically to help advance reaction design. By capitalizing on the efficiency of dirhodium-catalyzed intermolecular C--H amination reactions, we have developed a novel strategy for constructing saturated azacycles from readily available precursors. The preparation of substituted azetidines and larger ring, nitrogen-containing saturated heterocycles is enabled through efficient and selective intermolecular sp3-C--H amination of alkyl bromide derivatives. A range of substrates are demonstrated to undergo C--H amination and subsequent sulfamate alkylation in good to excellent yield. N-Phenoxysulfonyl-protected products can be unmasked under neutral or mild basic conditions to yield the corresponding cyclic secondary amines. The preparative convenience of this protocol is demonstrated through gram-scale and telescoped multistep procedures. Application of this technology is highlighted in a nine-step total synthesis of an unusual azetidine-containing natural product, penaresidin B.

Download or read book Applied Cross-Coupling Reactions written by Yasushi Nishihara and published by Springer Science & Business Media. This book was released on 2012-12-14 with total page 247 pages. 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.

Book Synopsis Rhodium-Catalyzed Enantioselective Desymmetrizations of Oxabicyclic Alkenes and Alkene Difunctionalization Via Nickel-Catalyzed Arylcyanation by : Andy Wei Jen Yen
Download or read book Rhodium-Catalyzed Enantioselective Desymmetrizations of Oxabicyclic Alkenes and Alkene Difunctionalization Via Nickel-Catalyzed Arylcyanation written by Andy Wei Jen Yen and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis of heterocycles using transition metal catalysis is a topic of broad interest in the field of organic chemistry. Transition metal catalysts allow many diverse bond disconnections to be realized, allowing for many ways to assemble heterocycles. Many of the transformations developed in the Lautens group are aimed at atom economical bond construction processes that streamline synthesis and minimize waste. The arylcyanation reaction and the asymmetric ring opening (ARO) reaction are two examples of methods developed in our group that embody this design principle. Chapter 1 of this thesis describes the development of a nickel-catalyzed arylcyanation reaction for the synthesis of 3,3-disubstituted oxindoles. This method was inspired by our work on the palladium-catalyzed arylcyanation reaction, originally developed to address challenges in the formal synthesis of (+)-corynoline. This nickel-catalyzed reaction uses an air-stable catalyst precursor to achieve a highly practical synthesis of a nitrile-containing oxindole via a domino Heck-cyanide capture cascade. Derivatizations of the nitrile group affords a series of novel heterocyclic scaffolds. Chapter 2 details the discovery and development of a novel enantioselective cycloisomerization reaction of oxabicyclic alkenes. Our work on developing the intramolecular asymmetric ring opening reaction led to the discovery of a novel epoxide synthesis. Specifically, when bridgehead substituted oxabicyclic alkenes with non-nucleophilic side chains are reacted with the [Rh(cod)2]OTf/PPF-PtBu2 catalyst in the absence of an external nucleophile, chiral epoxides are obtained. The synthesis of epoxides through cycloisomerization reactions possesses 100% atom economy and avoids the use of external oxidant. Chapter 3 describes an asymmetric ring opening reaction, specifically to address gaps in the methodology concerning amine nucleophiles. We were inspired by our group's previous attempts to use amino acid derived nucleophiles in the ARO reaction. We developed a way to incorporate amino acids into the ARO reaction by employing their 2-nitrobenzenesulfonamide (nosyl) derivatives as pronucleophiles. Intriguingly, we observed a divergence in reactivity between the diastereomeric hydroxyester products, in that one diastereomer was capable of lactonization and the other was not. This led to the enantioselective synthesis of chiral oxazinones, which are similar to the naphthoxazine class of compounds which possess dopaminergic activity.
