A broad-spectrum, catalytic method has been developed for the synthesis of sulfonamides and sulfamates. With the activation by the combination of a catalytic amount of 1-hydroxybenzotriazole (HOBt) and silicon additives, amidations of sulfonyl fluorides and fluorosulfates proceeded smoothly and excellent yields were generally obtained (87-99 %). Noticeably, this protocol is particularly efficient for sterically hindered substrates. Catalyst loading is generally low and only 0.02 mol % of catalyst is required for the multidecagram-scale synthesis of an amantadine derivative. In addition, the potential of this method in medicinal chemistry has been demonstrated by the synthesis of the marketed drug Fedratinib via a key intermediate sulfonyl fluoride 13. Since a large number of amines are commercially available, this route provides a facile entry to access Fedratinib analogues for biological screening.

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.

The combination of transition-metal catalysis and organocatalysis increasingly offers chemists opportunities to realize diverse unprecedented chemical transformations. By combining iridium with chiral thiourea catalysis, direct enantioselective reductive cyanation and phosphonylation of secondary amides have been accomplished for the first time for the synthesis of enantioenriched chiral alpha-aminonitriles and alpha-aminophosphonates. The protocol is highly efficient and enantioselective, providing a novel route to the synthesis of optically active alpha-functionalized amines from the simple, readily available feedstocks. In addition, the reactions are scalable and the thiourea catalyst can be recycled and reused.

When treated with an alkoxide base like t-BuOK in aprotic solvent, N-diphenylmethyl imino oxindoles, made conveniently through condensation of corresponding isatins with N-diphenylmethyl amine, are deprotonated to form azaallyl anions. Allylation and alkylation of this type of intermediates proceed smoothly with diverse C-electrophiles. Acidic work up finishes 3-amino-3-allyl/alkyl oxindoles. The overall transformation equals to an umpolung process at the C3 of isatins. (c) 2021 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.

A practical and scalable electrochemical oxidation of S-H and N-H was developed. This oxidant-and catalyst-free electrochemical process enables S-N bond formation with inexpensive nickel electrodes in an undivided cell. This procedure exhibits broad substrate scopes and good functional-group compatibility. A 50 g scale oxidative coupling augurs well for industrial applications.

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.

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.

We report the synthesis of alpha-aminonitriles by one-pot coupling reaction of aldehyde, amines and trimethylsilyl cyanide (TMSCN) using beta-ketoiminato zinc complexes as a pre-catalyst in very good yield under mild reaction condition. Homoleptic zinc complex [{kappa(2)-(2,4,6-Me3C6H2NC(Me)=CHC(Me)=O)}(2)Zn] (1 a) was synthesized by the treatment of protic ligand [(2,4,6-Me3C6H2NHC(Me)=CHC(Me)=O)] ((LH)-H-1) with potassium hydride and anhydrous zinc diiodide in 2 : 2 : 1 molar ratio in THF. Analogous reactions using [(2,6-(Pr2C6H3NHC)-Pr-i(Me)=CHC(Me)=O)] ((LH)-H-2) and [(Ph2CHNHC(Me)=CHC(Me)=O)] ((LH)-H-3) as protic ligands, dinuclear zinc complexes [{kappa(3)-(2,6-(Pr2C6H3NC)-Pr-i(Me)=CHC(Me)=O)}ZnI](2)(1 b) and [Zn(Ph2CHNHC-(Me)=CHC(Me)=O)ZnI2] (1 c) were obtained in good yield. Molecular structures of ligandsL(1)H,(LH)-H-3, and zinc complexes1 a,1 b, and1 cwere established by single-crystal x-ray diffraction analysis. Dinuclear zinc complexes1 b, and1 cexhibited high transformation, greater selectivity and broad substrate scope for the synthesis of alpha-aminonitrile under mild condition. A most plausible mechanism for synthesis alpha-aminonitrile is proposed based on several controlled reactions.

Herein, we broaden the application scope of (cyclopentadienone)iron complexes 1 in C=N bond reduction. The catalytic scope of pre-catalyst 1b, which is more active than the Knolker complex (1a) and other members of its family, has been expanded to the catalytic transfer hydrogenation (CTH) of a wider range of aldimines and ketimines, either pre-isolated or generated in situ. The kinetics of 1b-promoted CTH of ketimine S1 were assessed, showing a pseudo-first order profile, with TOF = 6.07 h(-1) at 50 % conversion. Moreover, the chiral complex 1c and its analog 1d were employed in the enantioselective reduction of ketimines and reductive amination of ketones, giving fair to good yields and moderate enantioselectivity.

The NLRP3 inflammasome is a component of the innate immune system involved in the production of proinflammatory cytokines. Aberrant activation by a wide range of exogenous and endogenous signals can lead to chronic, low-grade inflammation. It has attracted a great deal of interest as a drug target due to the association with diseases of large unmet medical need such as Alzheimer’s disease, Parkinson’s disease, arthritis, and cancer. To date, no drugs specifically targeting inhibition of the NLRP3 inflammasome have been approved. In this work, we used the known NLRP3 inflammasome inhibitor CP-456,773 (aka CRID3 or MCC 950) as our starting point and undertook a Structure-Activity Relationship (SAR) analysis and subsequent scaffold-hopping exercise. This resulted in the rational design of a series of novel ester-substituted urea compounds that are highly potent and selective NLRP3 inflammasome inhibitors, as exemplified by compounds 44 and 45. It is hypothesized that the ester moiety acts as a highly permeable delivery vehicle and is subsequently hydrolyzed to the carboxylic acid active species by carboxylesterase enzymes. These molecules are greatly differentiated from the state-of-the-art and offer potential in the treatment of NLRP3-driven diseases, particularly where tissue penetration is required.
