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.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalytic methods for C(sp3)--H amination are enabling technologies for both the synthesis and late-stage diversification of myriad organic molecules. Contemporary challenges that propel future development of such processes are presented by complex substrates approximating the architectures found in natural products along with polar, functional group-rich active pharmaceutical and agrochemical ingredients. In our efforts to address these limitations, we have established a catalytic system for C--H amination that markedly advances the ability of chemists to efficiently introduce nitrogen into molecules of different structural types. The discovery of pivalonitrile (t-BuCN) as a differential solvent for Rh-catalyzed intermolecular amination of C(sp3)--H bonds and phenyl sulfamate (PhsNH2) as a nitrene precursor has enabled efficient functionalization of a wide variety of complex molecule substrates including natural products and active pharmaceutical ingredients (APIs). Although limitations remain with oxidatively labile functional groups, including basic amines, our disclosure represents a definitive leap forward in the state-of-the-art for C--H bond oxidation. Mechanistic data strongly implicate a pathway for catalyst decomposition that initiates with solvent oxidation, thus providing rationale for the marked influence of pivalonitrile on this reaction process. The phenyl sulfamate nitrogen source can be unmasked under mild conditions using pyridine and water to unveil the corresponding primary amine products. Additionally, through amination of bromoalkane and mesyloxalkane substrates, SN2 cyclization can afford azetidines and other saturated azacycles in good to excellent yield. In pursuit of alternative, modular methods for the installation of sulfamate and sulfamide groups, we have developed pentafluorophenyl sulfamate (PfpsNH2) and trichlorphenyl sulfmatate (TcpsNH2) as bench-stable, versatile reagents for sulfamoylation of alcohol and amine nucleophiles to generate N-unsubstituted sulfamates and sulfamides. This type of 'click' reaction should find widespread use in academic and industrial labs.

The Davies group is interested in the development of chiral dirhodium catalysts and their utilization in donor/acceptor diazo decomposition reactions. Rh 2 (S -DOSP) 4 catalyzed intermolecular carbenoid transformations lead to diverse products with excellent selectivity. The first chapter of this thesis explores the limitations of the currently available dirhodium catalysts and the design and synthesis of novel phthalamide-based dirhodium catalysts. Applications of these new catalysts in various carbenoid reactions are discussed. The second chapter focuses on the development of an asymmetric methodology for the synthesis of tropanes by rhodium-catalyzed [4+3] cycloaddition. This methodology has been extended to a range of electronically and structurally diverse pyrroles and furans. This asymmetric tandem cyclopropanation Cope rearrangement was then successfully applied in a key step of the enantioselective synthesis of ( - )-isostemofoline. The third chapter describes the development of asymmetric amination methodology using chiral dirhodium catalysts and their applications in both intramolecular as well as intermolecular amination reactions.

Available in PDF, EPUB and Kindle. Book excerpt: Amines are very important intermediates for chemical industry and life science, which can be synthesized through different traditional routes. Metals based catalytic amination of alcohols via the so-called “hydrogen borrowing” mechanism is a relative efficient and environmental benign way for synthesis of different primary amines. However, there are still some challenges exist, such as high cost of noble metals, low selectivity of primary amine products, and poor stability and recyclability for industrial applications. To solve these problems, different strategies have been applied in this thesis. Carbon deposition produced by catalyst pre-treatment with alcohols under the optimized conditions has been employed for major enhancement of the selectivity of alcohol amination to primary amines (from 30-50 to 80-90%), which arises from steric hindrance in hydrogenation of bulky secondary imines as intermediate products over partially carbon-decorated cobalt nanoparticles. An efficient approach to protect cobalt catalyst from catalytic deactivation by liquid bismuth promotion with different loading content was disclosed for selectively amination of 1-octanol. The N-alkylation of amines by alcohols over a cheap and efficient heterogeneous catalyst-titanium hydroxide was also proposed. The catalyst with mild Brönsted acidity provides the selectivity higher than 90% to secondary amines for functionalized aromatic and aliphatic alcohols and amines at high catalytic activity and stability.

Book excerpt: This book looks at new ways of tackling the problem of separating reaction products from homogeneous catalytic solutions. The new processes involve low leaching supported catalysts, soluble supports such as polymers and dendrimers and unusual solvents such as water, fluorinated organics, ionic liquids and supercritical fluids. The advantages of the different possibilities are discussed alongside suggestions for further research that will be required for commercialisation. Unlike other books, in addition to the chemistry involved, the book looks at the process design that would be required to bring the new approaches to fruition. Comparisons are given with existing processes that have already been successfully applied and examples are given where these approaches are not suitable. The book includes: - New processes for the separation of products from solutions containing homogeneous catalysts - Catalysts on insoluble or soluble supports – fixed bed catalysts - continuous flow or ultrafiltration - Biphasic systems: water - organic, fluorous - organic, ionic liquid – organic, supercritical fluids (monophasic or biphasic with water, organic or ionic liquid) - Comparisons with current processes involving atmospheric or low temperature distillation - Consideration of Chemistry and Process Design - Advantages and disadvantages of each process exposed - Consideration of what else is need for commercialisation
