[PMID: 39236162 DOI: 10.1126/science.ado8027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 05/31/2024] [Accepted: 07/31/2024] [Indexed: 09/07/2024]
Abstract
Transition metal-catalyzed cross-couplings have great potential to furnish complex ethers; however, challenges in the C(sp3)-O functionalization step have precluded general methods. Here, we describe computationally guided transition metal-ligand design that positions a hydrogen-bond acceptor anion at the reactive site to promote functionalization. A general cross-coupling of primary, secondary, and tertiary aliphatic alcohols with terminal olefins to furnish >130 ethers is achieved. The mild conditions tolerate functionality that is prone to substitution, elimination, and epimerization and achieve site selectivity in polyol settings. Mechanistic studies support the hypothesis that the ligand's geometry and electronics direct positioning of the phosphate anion at the π-allyl-palladium terminus, facilitating the phosphate's hydrogen-bond acceptor role toward the alcohol. Ligand-directed counteranion positioning in cationic transition metal catalysis has the potential to be a general strategy for promoting challenging bimolecular reactivity.

Abstract
Polyfunctionalized arenes are privileged structural motifs in both academic and industrial chemistry. Conventional methods for accessing this class of chemicals usually involve stepwise modification of phenyl rings, often necessitating expensive noble metal catalysts and suffering from low reactivity and selectivity when introducing multiple functionalities. We herein report dehydrogenative synthesis of N-functionalized 2-aminophenols from cyclohexanones and amines. The developed reaction system enables incorporating amino and hydroxyl groups into aromatic rings in a one-shot fashion, which simplifies polyfunctionalized 2-aminophenol synthesis by circumventing issues associated with traditional arene modifications. The wide substrate scope and excellent functional group tolerance are exemplified by late-stage modification of complex natural products and pharmaceuticals that are unattainable by existing methods. This dehydrogenative protocol benefits from using 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) as oxidant that offers interesting chemo- and regio-selective oxidation processes. More notably, the essential role of in situ generated water is disclosed, which protects aliphatic amine moieties from overoxidation via hydrogen bond-enabled interaction.

Abstract
The construction of Csp3-Csp3 bonds through Negishi-type reactions using alkylzinc reagents as the pronucleophiles is of great importance for the synthesis of pharmaceuticals and agrochemicals. However, the use of air and moisture sensitive solutions of conventional alkylzinc halides, which show unsatisfying reactivity and limitation of generality in twofold Csp3-Csp3 cross-couplings, still represents drawbacks. We herein report the first preparation of solid and salt-stabilized alkylzinc pivalates by OPiv-coordination, which exhibit enhanced stability and a distinct advantage of reacting well in cobalt-catalyzed difluoroalkylation-alkylation of dienoates, thus achieving the modular and site-selective installation of CF2- and Csp3-groups across double bonds in a stereoretentive manifold. This reaction proceeds under simple and mild conditions and features broad substrate scope and functional group compatibility. Kinetic experiments highlight that OPiv-tuning on the alkylzinc pivalates is the key for improving their reactivity in twofold Csp3-Csp3 cross-couplings. Furthermore, facile modifications of bioactive molecules and fluorinated products demonstrate the synthetical utility of our salt-stabilized alkylzinc reagents and cobalt-catalyzed alkyldifluoroalkylation protocol.

Abstract
Cyclopropanes are important substructures in natural products and pharmaceuticals. Although traditional methods for their incorporation rely on cyclopropanation of an existing scaffold, the advent of transition-metal catalysis has enabled installation of functionalized cyclopropanes using cross-coupling reactions. The unique bonding and structural properties of cyclopropane render it more easily functionalized in transition-metal-catalysed cross-couplings than other C(sp3) substrates. The cyclopropane coupling partner can participate in polar cross-coupling reactions either as a nucleophile (organometallic reagents) or as an electrophile (cyclopropyl halides). More recently, single-electron transformations featuring cyclopropyl radicals have emerged. This Review will provide an overview of transition-metal-catalysed C-C bond formation reactions at cyclopropane, covering both traditional and current strategies, and the benefits and limitations of each.

Abstract
Grignard reagents are commonly used as carbanion equivalents. Herein, we report an example of Grignard reagents acting as halide nucleophiles to form alkyl iodides and bromides. We establish that Grignard reagents can convert alkyl mesylates into alkyl halides, as well as be employed in a one-pot halogenation reaction starting from alcohols, which proceed through mesylate intermediates. The halogenation reaction is confirmed to occur by an SN2 pathway with inversion of configuration and is demonstrated to be efficient on multi-gram scale.

Abstract
A palladium-catalyzed cross-coupling of 3-iodoazetidines and nonheteroaryl boronic acids was reported. The [1,1'-biphenyl]-2-yldicyclohexylphosphane ligand enabled the reaction that favored the formation of 2-aryl azetidines. The control experiments indicated that the reaction can proceed through either a palladium-hydride/dihydroazete complex or free dihydroazete intermediate followed by hydropalladation.

Abstract
A total of 16 oxidizing reagents were screened to compare their oxidation selectivities for axial and equatorial hydroxyl moieties using steroidal methyl chenodeoxycholate, methyl deoxycholate, and 4-tert-butylcyclohexanol (cis/trans 1:1 mixture). These compounds were selected for their stable chair conformations. The results of our study demonstrated that, for the oxidation of a scaffold bearing both axial and equatorial hydroxyl groups, nitroxide-radical-based reagents should be the first choice if oxidation of the equatorial hydroxyl group is needed and Stevens or Dess-Martin reagents should be the first choice for the preferential oxidation of the axial hydroxyl group.

Abstract
Functionalized enantiopure organosilanes are important building blocks with applications in various fields of chemistry; nevertheless, asymmetric synthetic methods for their preparation are rare. Here we report the first organocatalytic enantioselective synthesis of tertiary silyl ethers possessing "central chirality" on silicon. The reaction proceeds via a desymmetrizing carbon-carbon bond forming silicon-hydrogen exchange reaction of symmetrical bis(methallyl)silanes with phenols using newly developed imidodiphosphorimidate (IDPi) catalysts. A variety of enantiopure silyl ethers was obtained in high yields with good chemo- and enantioselectivities and could be readily derivatized to several useful chiral silicon compounds, leveraging the olefin functionality and the leaving group nature of the phenoxy substituent.

Abstract
Metal-catalyzed cross-couplings have emerged as essential tools for the construction of C-C bonds. The identification of efficient catalytic systems as well as large substrate scope made these cross-couplings key reactions to access valuable molecules ranging from materials, agrochemicals to active pharmaceutical ingredients. They have been increasingly integrated in retrosynthetic plans, allowing shorter and original route development. Palladium-catalyzed cross-couplings still largely rule the field, with the most popular reactions in industrial processes being the Suzuki and Sonogashira couplings. However, the extensive use of palladium complexes raises several problems such as limited resources, high cost, environmental impact, and frequent need for sophisticated ligands. As a consequence, the use of nonprecious and cheap metal catalysts has appeared as a new horizon in cross-coupling development. Over the last three decades, a growing interest has thus been devoted to Fe-, Co-, Cu-, or Ni-catalyzed cross-couplings. Their natural abundance makes them cost-effective, allowing the conception of more sustainable and less expensive chemical processes, especially for large-scale production of active molecules. In addition to these economical and environmental considerations, the 3d metal catalysts also exhibit complementary reactivity with palladium complexes, facilitating the use of alkyl halide partners due to the decrease of β-elimination side reactions. In particular, by using cobalt catalysts, numerous cross-couplings between alkyl halides and organometallics have been described. However, cobalt catalysis still stays far behind palladium catalysis in terms of popularity and applications, and the expansion of the substrate scope as well as the development of simple and robust catalytic systems remains an important challenge.In 2012, our group entered the cobalt catalysis field by developing a cobalt-catalyzed cross-coupling between C-bromo glycosides and Grignard reagents. The generality of the coupling allowed the preparation of a range of valuable C-aryl and C-vinyl glycoside building blocks. We then focused on the functionalization of saturated N-heterocycles, and a variety of halo-azetidines, -pyrrolidines, and -piperidines were successfully reacted with aryl and alkenyl Grignard reagents under cobalt catalysis. With the objective of preparing valuable α-aryl amides, a cobalt-catalyzed cross-coupling applied to α-bromo amides was studied and then extended to α-bromo lactams. Recently, we also reported an efficient and general cross-coupling involving cyclopropyl- and cyclobutyl-magnesium bromides. This method allows the alkylation of functionalized small strained rings by a range of primary and secondary alkyl halides.

Abstract
A cobalt-catalyzed asymmetric cross-coupling of α-bromo-α-fluorotoluene derivatives with a variety of aryl zincates derived from lithium aryl n-butyl pinacol boronates and ZnBr2 under mild reaction conditions was described. In addition to mild reaction conditions, another advantage includes the compatibility of various common functional groups such as fluoride, chloride, bromide, cyano, or ester groups. Furthermore, this protocol was successfully applied to the enantioselective synthesis of three fluorinated derivatives of biologically active compounds or drug molecules.

Abstract
A one-pot iodo-cyclization/transition metal-catalyzed cross-coupling sequence is reported to access various C5-functionalized oxazolidin-2-ones from unsaturated N-Boc-allylamines. Depending on the Grignard reagents used for the cross-coupling, e.g., aryl- or cyclopropylmagnesium bromide, a cobalt or copper catalyst has to be used to obtain the functionalized oxazolidin-2-ones in good yields.

Abstract
Strain-release-driven methodology is a powerful tool for accessing structural motifs, highly desirable by the pharmaceutical industry. The reactivity of spring-loaded cyclic reagents is dominated by transformations relying on their inherent electrophilic reactivity. Herein, we present a polarity-reversal strategy based on light-driven cobalt catalysis, which enables the generation of nucleophilic radicals through strain release. The applicability of this methodology is demonstrated by the design of two distinct types of reactions: Giese-type addition and Co/Ni-catalyzed cross-coupling. Moreover, a series of electrochemical, spectroscopic, and kinetic experiments as well as X-ray structural analysis of the intermediate alkylcobalt(III) complex give deeper insight into the mechanism of the reaction.
