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.

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.

This book was released on 2014 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dirhodium complexes have a long-standing importance in C8́2H functionalization chemistry, but little is known about the reactive intermediates on which this chemistry relies. The first part of this dissertation focuses on intermediates in catalytic C8́2H amination chemistry: In Chapter 3, the catalyst Rh2(esp)2 (esp = [alpha], [alpha], [alpha]', [alpha]' -tetramethyl- 1,3-benzenedipropanoate) is studied spectroscopically and electrochemically to gain insight into its robust nature. These studies implicate the stability of a one-electron oxidized Rh2II,III state in the high level of activity reported for this catalyst. In Chapter 4, two complexes that are structurally analogous to Rh2(esp)2 with chelating dicarboxylate ligands based on a resorcinol backbone are synthesized. These new complexes are electronically dissimilar to Rh2(esp)2, since the ligands are more readily oxidized than the Rh2 core, as observed by cyclic voltammetry. In catalytic studies, it is shown that these new catalysts perform equally well in intramolecular amination as parent catalyst Rh2(esp)2, but fail to achieve the same level of efficiency in intermolecular amination. The results of this study further implicate the importance of mixed-valency in intermolecular amination. In Chapter 5, the synthesis and catalytic activity of a new purposefully mixed-valent Rh2-amidate catalyst is reported. The new catalyst, Rh2(espn)2Cl (espn = [alpha], [alpha], [alpha]', [alpha]' -tetramethyl-1,3-benzenedipropanamidate), achieves higher turnover numbers in intramolecular amination than parent catalyst Rh2(esp)2. Chapter 6 is focused on the exploration of intermediates in Rh2-mediated carbenoid chemistry. Methods for preparing a metastable solution of a donor/acceptor carbene complex of Rh2(TPA)4 (TPA = triphenylacetate) are described; the carbenoid intermediate is characterized by NMR, resonance Raman and X-ray absorption spectroscopies, all corroborated by DFT analysis. In summary, the work presented in this dissertation establishes the importance of mixed-valency for increased turnover in C8́2H amination catalysts. Isolation of the first Rh2-carbenoid provides experimental support for the previously theoretically-based catalytic reactivity of Rh2-carbenoids.

Available in PDF, EPUB and Kindle. Book excerpt: The studies presented in this dissertation are regarding the development of new methods for copper-catalyzed carbon-heteroatom bond formations, including asymmetric hydroamination and continuous-flow aromatic Finkelstein reaction. The first part of this dissertation focuses on the development of copper-catalyzed asymmetric hydroamination reactions to access various classes of enantioenriched amines. This includes the development of a broadly applicable hydroamination protocol for the synthesis of enantioenriched N-arylamines (Chapter 1) and 1,2- diamines (Chapter 2). The second part of this dissertation describes the development of copper-catalyzed aromatic Finkelstein reaction under continuous-flow conditions (Chapter 3). Part I. Chapter 1. A Modified System for the Synthesis of Enantioenriched N-Arylamines through Copper-Catalyzed Hydroamination Despite significant recent progress in copper-catalyzed enantioselective hydroamination chemistry, the synthesis of chiral N-arylamines, which are frequently found in natural products and pharmaceuticals, has not been realized. Initial experiments with N-arylhydroxylamine ester electrophiles were unsuccessful and instead, their reduction, in the presence of copper hydride (CuH) catalysts, was observed. We detail key modifications of our previously reported hydroamination protocols that led to broadly applicable conditions for the enantioselective net addition of secondary anilines across the double bond of styrenes, 1,1 -disubstituted alkenes, and terminal alkenes. NMR studies suggest that suppression of the undesired reduction pathway is the basis for the dramatic improvements in yield under this new protocol. Chapter 2. Regio- and Enantioselective Synthesis of 1,2-Diamine Derivatives by Copper- Catalyzed Hydroamination A highly regio- and enantioselective synthesis of 1,2-diamines using [gamma]-substituted allylic pivalamides via copper-catalyzed hydroamination is reported. The N-pivaloyl group is essential, both in facilitating the hydrocupration step and in suppressing the unproductive [beta]-elimination from the alkylcopper intermediate. This synthetic approach enables an efficient construction of chiral, differentially protected, vicinal diamines under mild conditions with broad functional group tolerance. Part II. Chapter 3. Rapid and Efficient Copper-Catalyzed Finkelstein Reaction of (Hetero)Aromatics under Continuous-Flow Conditions A general, rapid, and efficient method for the copper-catalyzed Finkelstein reaction of (hetero)aromatics has been developed using continuous flow to generate a variety of aryl iodides. The described method can tolerate a broad range of functional groups, including N-H and O-H groups. Additionally, in lieu of isolation, the aryl iodide products in solution can be directly used in two distinct multistep continuous-flow processes (amidation or Mg-I exchange/nucleophilic addition) to demonstrate the flexibility of this method.
