Reusable catalysts based on earth-abundant metals with a broad applicability in organic synthesis are a key to a more sustainable production of fine chemicals, pharmaceuticals and agrochemicals. Herein, we report on a nanostructured nickel catalyst for the general and selective synthesis of primary amines via reductive amination, employing ammonia dissolved in water. Our catalyst, which operates at low temperature and pressure, is highly active, reusable and easy to handle. The synthesis from a specific nickel complex and gamma-Al2O3 is straightforward, with the ligand-metal combination of this complex being crucial. Aldehydes (including purely aliphatic ones), aryl-alkyl, dialkyl and diaryl ketones can all be converted smoothly into primary amines. In addition, the amination of pharmaceuticals, bioactive compounds and natural products is demonstrated. Many functional groups-including hydrogenation-sensitive examples-are tolerated. We expect that our findings will inspire others to develop reusable and nanostructured earth-abundant metal catalysts for complex organic transformations.

N,N’-Acetals are sensitive compounds, and the challenging asymmetric synthesis of acyclic N,N’-acetals by the general addition of amines to ketimines has never been reported so far. In this study, highly enantioselective addition of aryl amines to isatin-derived ketimines catalyzed by chiral urea derived from quinine was developed. A series of new acyclic N,N’-acetals were constructed by this protocol in high to excellent yields (78-99%) and high to excellent enantioselectivities (76-96% ee).

Small molecule mitochondrial uncouplers have recently garnered great interest for their potential in treating nonalcoholic steatohepatitis (NASH). In this study, we report the structure-activity relationship profiling of a 6-amino[1,2,5]oxadiazolo[3,4-b]pyrazin-5-ol core, which utilizes the hydroxy moiety as the proton transporter across the mitochondrial inner membrane. We demonstrate that a wide array of substituents is tolerated with this novel scaffold that increased cellular metabolic rates in vitro using changes in oxygen consumption rate as a readout. In particular, compound SHS4121705 (12i) displayed an EC50 of 4.3 mu M in L6 myoblast cells and excellent oral bioavailability and liver exposure in mice. In the STAM mouse model of NASH, administration of 12i at 25 mg kg(-1) day(-1) lowered liver triglyceride levels and improved liver markers such as alanine aminotransferase, NAFLD activity score, and fibrosis. Importantly, no changes in body temperature or food intake were observed. As potential treatment of NASH, mitochondrial uncouplers show promise for future development.

Inhibition of coronavirus (CoV)-encoded papain-like cysteine proteases (PLpro) represents an attractive strategy to treat infections by these important human pathogens. Herein we report on structure-activity relationships (SAR) of the noncovalent active-site directed inhibitor (R)-5-amino-2-methyl-N-(1-(naphthalen-1-yl)ethyl) benzamide (2 b), which is known to bind into the S3 and S4 pockets of the SARS-CoV PLpro. Moreover, we report the discovery of isoindolines as a new class of potent PL(pro)inhibitors. The studies also provide a deeper understanding of the binding modes of this inhibitor class. Importantly, the inhibitors were also confirmed to inhibit SARS-CoV-2 replication in cell culture suggesting that, due to the high structural similarities of the target proteases, inhibitors identified against SARS-CoV PL(pro)are valuable starting points for the development of new pan-coronaviral inhibitors.

A 5-endo trig oxidative radical cyclization of benzylamine-derived Ugi three-component reaction products rapidly affords imidazolidinones with three diversity elements. This adaptation of our previously described multicomponent reactionoxidation methodology further showcases manipulation of the diversity elements in multicomponent reaction products via oxidative radical cyclizations, which generates highly decorated privileged heterocycles.

An in situ formed cobalt catalyst is developed from cobalt(II)bromide, bis[2-(diisopropylphosphino)-4-methylphenyl]amine and zinc metal. The catalyst mediates the acceptorless dehydrogenative coupling of alcohols and amines into imines with the release of hydrogen gas and the transformation is applied to the synthesis of a variety of imines from different alcohols and amines. The mechanism is investigated with labelled substrates and based on the results a cobalt(I) PNP complex is believed to be the catalytically active species which abstracts hydrogen gas from the alcohol through a metal ligand bifunctional pathway.

A metal-free transamidation of primary amides was developed. Trimethylsilyl chloride (TMSCl) acted as the activator in transamidation. In the presence of TMSCl, primary amides reacted with primary amines to yield transamidated secondary amides in NMP solvent. The transamidation of benzamide with secondary amines for the formation of tertiary amides succeeds in an NMP/CHCl3 solvent mixture.

Three novel hexacoordinated nickel catalysts containing salicylaldbenzhydrylimine ligand and tetrahydrofuran heterocycle, Ni{(THF) (3-R-1) (5-R-2)C6H2(O)CHNCH(C6H5)(2)}(2), (R-1 = Br, R-2 = H, Ni1; R-1 = Br, R-2 = Br, Ni2; R-1 = Cl, R-2 = Cl, Ni3.), were synthesized and their molecular structures were confirmed by X-ray crystallography. Ni1-Ni3 catalysts exhibited high activities (0.53-2.11 x 10(6) g(polymer)/mol(Ni).h) toward norbornene homopolymerization and high activity (0.29-2.62 x 10(5) g(polymer)/mol(Ni).h) to copolymerization of norbornene and 1-hexene. When the 1-hexene feed ratio was changed from 10 to 70%, the 1-hexene content in the obtained copolymers could be controlled to 8.23-26.58%. The Ni3 with R-1 and R-2 were both electron withdrawing groups (-Cl) on the aromatic ring of salicylaldehyde, showed the highest activity as well as the highest 1-hexene insert ratios. At the same time, only a small amount of B(C6F5)(3) cocatalyst (5 x 10(-5) mol) need to be consumed in the copolymerization process. In addition, the obtained copolymers had a high thermal decomposition temperature (T-d > 386 degrees C) and a low glass transition temperature (T-g = 208.67-237.42 degrees C), which showed that the processability of these polymers was improved while the high thermal decomposition temperature was kept. The copolymers also exhibited good solubility in general organic solvents and high optical transparency in the visible region. (C) 2020 Elsevier B.V. All rights reserved.

Without using chiral sources, the Strecker reaction of achiral hydrogen cyanide, p-tolualdehyde and benzhydrylamine gave enantioenriched L- or D-N-benzhydryl-alpha-( p-tolyl) glycine nitriles with up to > 99% ee in a mixed solvent of water and methanol. Therefore, total spontaneous resolution of alpha-aminonitriles could occur through a prebiotic mechanism of alpha-amino acid synthesis. Moreover, it was demonstrated that the repetition of partial dissolution and crystallization of a suspended conglomerate of aminonitrile under solution-phase racemization could generate the enantiomeric imbalance to afford, in combination with the amplification of chirality, an enantioenriched product in every case. Among the 73 experiments that were carried out, D-and L-enriched isomers occurred 36 and 37 times, respectively. This stochastic behavior, under achiral or racemic starting conditions, meets the requirements of the spontaneous absolute asymmetric Strecker synthesis. The implications of the present results for the origin of chirality of alpha-amino acids are discussed.

Aliphatic amines strongly coordinate, and therefore easily inhibit, the activity of transition-metal catalysts, posing a marked challenge to nitrogen-hydrogen (N-H) insertion reactions. Here, we report highly enantioselective carbene insertion into N-H bonds of aliphatic amines using two catalysts in tandem: an achiral copper complex and chiral amino-thiourea. Coordination by a homoscorpionate ligand protects the copper center that activates the carbene precursor. The chiral amino-thiourea catalyst then promotes enantioselective proton transfer to generate the stereocenter of the insertion product. This reaction couples a wide variety of diazo esters and amines to produce chiral alpha-alkyl alpha-amino acid derivatives.
