Zhang, Ninghui published the artcileNickel-Catalyzed C(sp3)-H Functionalization of Benzyl Nitriles: Direct Michael Addition to Terminal Vinyl Ketones, Computed Properties of 1205-17-0, the main research area is terminal vinyl ketone benzyl nitrile nickel catalyst Michael addition; cyano phenylalkanone.

An efficient nickel(0)-catalyzed addition of benzyl nitriles to terminal vinyl ketones via C(sp3)-H functionalization was developed. The reaction provided a novel and efficient protocol for the synthesis of α-functionalized benzyl nitriles with a wide range of structural diversity under mild reaction conditions while obviating the use of a strong base. The work might be potentially useful toward the development of an enantioselective variant using chiral nitrogen ligands.

Kawasaki, Tairin published the artcileDehydrogenative Coupling of Benzylic and Aldehydic C-H Bonds, Application In Synthesis of 1205-17-0, the main research area is alkylarene aldehyde iridium nickel catalyst dehydrogenative cross coupling; aryl ketone preparation; methylamide aldehyde iridium nickel catalyst dehydrogenative cross coupling; amino ketone preparation.

A photoinduced dehydrogenative coupling reaction between benzylic and aldehydic C-H bonds was reported. When a solution of an alkylbenzene and an aldehyde in Et acetate was irradiated with visible light in the presence of iridium and nickel catalysts, a coupled α-aryl ketone was formed with evolution of dihydrogen. An analogous C-C bond forming reaction occurs between a C-H bond next to the nitrogen of an N-methylamide and an aldehydic C-H bond to produce an α-amino ketone. These reactions provide a straightforward pathway from readily available materials leading to valued structural motifs of pharmacol. relevance.

Hoshimoto, Yoichi published the artcileMain-Group-Catalyzed Reductive Alkylation of Multiply Substituted Amines with Aldehydes Using H2, Product Details of C11H12O3, the main research area is dichlorophenyl tetrafluorophenyl boron frustrated Lewis pair catalyzed reductive alkylation; main group catalyzed reductive alkylation multiply substituted amine aldehyde; imine preparation frustrated Lewis pair catalyzed hydrogenation; isoindolinone aminophthalic anhydride preparation; crystal mol structure dichlorophenyl tetrafluorophenyl boron frustrated Lewis pair; aminonitrophenoxy benzylaniline preparation crystal mol structure; benzylamino isobenzofurandione preparation crystal mol structure; benzylaminophthalic acid preparation crystal mol structure.

Given the growing demand for green and sustainable chem. processes, the catalytic reductive alkylation of amines with main-group catalysts of low toxicity and mol. hydrogen as the reductant would be an ideal method to functionalize amines. However, such a process remains challenging. Herein, a novel reductive alkylation system using H2 is presented, which proceeds via a tandem reaction that involves the B(2,6-Cl2C6H3)(p-HC6F4)2-catalyzed formation of an imine and the subsequent hydrogenation of this imine catalyzed by a frustrated Lewis pair (FLP). This reductive alkylation reaction generates H2O as the sole byproduct and directly functionalizes amines that bear a remarkably wide range of substituents including carboxyl, hydroxyl, addnl. amino, primary amide, and primary sulfonamide groups. The synthesis of isoindolinones and aminophthalic anhydrides has also been achieved by a one-pot process that consists of a combination of the present reductive alkylation with an intramol. amidation and intramol. dehydration reactions, resp. The reaction showed a zeroth-order and a first-order dependence on the concentration of an imine intermediate and B(2,6-Cl2C6H3)(p-HC6F4)2, resp. In addition, the reaction progress was significantly affected by the concentration of H2. These results suggest a possible mechanism in which the heterolysis of H2 is facilitated by the FLP comprising THF and B(2,6-Cl2C6H3)(p-HC6F4)2.

A novel green and efficient catalyst-free, mild one-pot, multicomponent synthetic strategy has been developed to construct substituted 3,4-dihydro-2H-benzo[b][1,4]oxazine. This reaction proceeds via in situ formation of Schiff-base followed by base mediated alkylation with phenacyl bromide/substituted phenacyl bromide, finally leading to intramol. cyclization to give a mixture of diastereomers with excellent diastereoselectivity (up to dr = 99:1), which were isolated as a single diastereomer in moderate to excellent yields (41-92%). Besides, this new versatile methodol. provides a wide scope for the synthesis of different functionally substituted benzoxazine scaffolds and can be further exploited as building blocks for the synthesis of multifaceted mol. structures, especially for pharmaceutical applications.

Kodo, Taiga published the artcileOrganophotoredox-catalyzed semipinacol rearrangement via radical-polar crossover, Quality Control of 104-01-8, the main research area is hydroxyethyl phthalic ester organophotoredox catalyst photochem decarboxylative semipinacol rearrangement; ethanone preparation; allyl alc electrophile organophotoredox catalyst photochem alkylative semipinacol rearrangement; propanone preparation.

The organophotoredox-catalyzed semipinacol rearrangement via radical-polar crossover (RPC) was reported. A phenothiazine-based organophotoredox catalyst facilitates the generation of an α-hydroxy non-benzylic alkyl radical followed by oxidation to the corresponding carbocation, which was exploited to undergo the semipinacol rearrangement. As a result, the photochem. approach enables decarboxylative semipinacol rearrangement of β-hydroxycarboxylic acid derivatives and alkylative semipinacol type rearrangement of allyl alcs. with carbon electrophiles, producing α-quaternary or α-tertiary carbonyls bearing sp3-rich scaffolds.

Satish, Sohal published the artcileDesign, synthesis and SAR of antitubercular benzylpiperazine ureas, Category: isoquinoline, the main research area is piperazine carboxamide preparation tuberculostatic SAR antibacterial antitumor docking; Antitubercular; Benzylpiperazine ureas; Lead compounds; QcrB inhibitors.

N-furfuryl piperazine ureas disclosed by scientists at GSK Tres Cantos were chosen as antimycobacterial hits from a phenotypic whole-cell screen. Bioisosteric replacement of the furan ring in the GSK Tres Cantos mols. with a Ph ring led to mol. I with an MIC of 1μM against Mtb H37Rv, low cellular toxicity (HepG2 IC50 ∼ 80μM), good DMPK properties and specificity for Mtb. With the aim of delineating the SAR associated with compound I, fifty-five analogs were synthesized and screened against Mtb. The SAR suggested that the piperazine ring, benzyl urea and piperonyl moieties were essential signatures of this series. Active compounds in this series were metabolically stable, have low cellular toxicity and were valuable leads for optimization. Mol. docking suggests these mols. occupy the Q0 site of QcrB like Q203.

Gao, Kai published the artcileNanoscale, automated, high throughput synthesis and screening for the accelerated discovery of protein modifiers, SDS of cas: 86-51-1, the main research area is protein modifier preparation combinatorial nanoscale; cyclic aromatic amidine aldehyde isocyanide Groebke Blackburn Bienayme reaction.

Hit finding in early drug discovery is often based on high throughput screening (HTS) of existing and historical compound libraries, which can limit chem. diversity, is time-consuming, very costly, and environmentally not sustainable. On-the-fly compound synthesis and in situ screening in a highly miniaturized and automated format has the potential to greatly reduce the medicinal chem. environmental footprint. Here, acoustic dispensing technol. has been used to synthesize a library in a 1536 well format based on the Groebke-Blackburn-Bienayme’ reaction (GBB-3CR) on a nanomole scale. The unpurified library was screened by differential scanning fluorimetry (DSF) and cross-validated using microscale thermophoresis (MST) against the oncogenic protein-protein interaction menin-MLL. Several GBB reaction products were found as μM menin binder, and the structural basis of the interactions with menin was elucidated by co-crystal structure anal. Miniaturization and automation of the organic synthesis and screening process can lead to an acceleration in the early drug discovery process, which is an alternative to classical HTS and a step towards the paradigm of continuous manufacturing
