Wang, Tao published the artcileA Metal-Free Direct Arene C-H Amination, COA of Formula: C8H10O2, the main research area is aryl amine preparation chemoselective; arene hydroxylamine amination.

Here, a metal-free arene e.g., mesitylene C-H amination using hydroxylamine derivatives 4-(CH3)C6H5S(O)2ON(R)R1 (R = H, Me; R1 = Me, Boc, Bn, etc.) under benign conditions was reported. A charge transfer interaction between the aminating reagents and the arene substrates enables the chemoselective amination of the arene, even in the presence of various functional groups. Oxygen was crucial for an effective conversion and its accelerating role for the electron transfer step was proven exptl. In addition, this was rationalized by a theor. study which indicated the involvement of a dioxygen-bridged complex with a “”Sandwich-like”” arrangement of the aromatic starting materials and the aminating agents at the dioxygen mol.

Zhang, Bing published the artcilePhoton-initiated heterogeneous redox couples for methylation of anilines under mild conditions, Product Details of C8H11NO, the main research area is carbon nitride supported palladium nanoparticle preparation surface structure; primary amine supported palladium nanoparticle catalyst photochem alkylation alkanol; alkyl secondary tertiary amine preparation green chem.

Methylation of anilines has drawn a lot of attention due to their valuable applications, and directly using methanol as a methylation reagent is of great advantage. Photon-initiated heterogeneous catalysis of this methylation process meets the requirements of green chem. It was shown that balanced redox zones within carbon nitride supported palladium nanoparticles boosted the selectivity of methylation of anilines under mild conditions.

Piehl, Patrick published the artcileEfficient methylation of anilines with methanol catalysed by cyclometalated ruthenium complexes, Synthetic Route of 5961-59-1, the main research area is methylaniline preparation; aniline methanol methylation ruthenium complex catalyst.

Cyclometalated ruthenium complexes, e.g., I, allow the effective methylation of anilines (R = 4-bromophenyl, 2-methylphenyl, 4-carbamoylphenyl, etc.) with methanol to selectively give N-methylanilines RNHCH3. This hydrogen autotransfer procedure proceeds under mild conditions (60°C) in a practical manner (NaOH as base). Mechanistic investigations suggest an active homogenous ruthenium complex and β-hydride elimination of methanol as the rate determining step.

Zhang, Shaochun published the artcileA pincer ligand enabled ruthenium catalyzed highly selective N-monomethylation of nitroarenes with methanol as the C1 source, Category: isoquinoline, the main research area is aryl amine preparation; nitroarene alc selective monomethylation tandem.

A straightforward and highly selective N-monomethylation of nitro compounds RNO2 (R = 4-methylphenyl, quinolin-6-yl, 9-oxo-9H-fluoren-1-yl, etc.) with methanol as the C1 source was developed by employing [RuCl2(p-cymene)2]2 as the catalyst and an NNN pincer (amine-pyridine-imine, API) as the ligand. This protocol was found to be highly selective and effective in the N-monomethylation of a broad spectrum of nitroarenes including pharmaceutically relevant nitro compounds with good tolerance of a set of functional groups. The mechanistic studies revealed that the reaction proceeded via a borrowing-hydrogen pathway in a one-pot cascade manner and methanol serves as both a hydrogen source and a methylation agent.

Yamashiro, Toshiki published the artcileCis-3-Azido-2-methoxyindolines as safe and stable precursors to overcome the instability of fleeting 3-azidoindoles, COA of Formula: C8H10O2, the main research area is arylindole preparation; arene azido alkoxyindole indium catalyst nucleophilic substitution; thioaryl indole preparation; thioarene azido alkoxyindole indium catalyst nucleophilic substitution; azido alkoxyindole preparation; bromo alkoxyindole diastereoselective azidation.

A general and concise approach for tackling this problem by using 3-azidoindole surrogated. The surrogated was bench-stable, presumably due to the observed intramol. O-Nβ bonding. The resultant fleeting intermediates underwent capturing in-situ to afford 3-substitued indoles through formal ipso-substitution of the azide group by nucleophiles. In these investigations, the fleeting 3-azidoindoles showed a C3-electrophilic character for the first time.

Based on systematic electrochem. anal., an integrated synthetic platform of C(sp3)-based organoboron compounds was established for the introduction of heteroatoms. The electrochem. mediated bond-forming strategy is highly effective for the functionalization of sp3-hybridized C atoms with significant steric hindrance. Also, virtually all the nonmetallic heteroatoms could be used as reaction partners using one unified protocol. The observed reactivity stems from the two consecutive single-electron oxidations of the substrate, which eventually generates an extremely reactive carbocation as the key intermediate. The detailed reaction profile could be elucidated through multifaceted electrochem. studies. Ultimately, a new dimension in the activation strategies for organoboron compounds was accomplished through the electrochem. driven reaction development.

Li, Ziyi published the artcileDynamic Covalent Reactions Controlled by Ring-Chain Tautomerism of 2-Formylbenzoic Acid, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is hydroxy isobenzofuroalc preparation; alc hydroxy isobenzofurone dynamic covalent reaction; isobenzofurothiol hydroxy preparation; thiol hydroxy isobenzofurone dynamic covalent reaction; isobenzofuroamine hydroxy preparation; amino hydroxy isobenzofurone dynamic covalent reaction.

The development of dynamic covalent reactions (DCRs) of common N-, O-, and S-mononucleophiles by controlling ring-chain tautomerism of 2-formylbenzoic acid was demonstrated. The regulation of distinct dual reactivity of interconverting open aldehyde and cyclic hemiacetal forms, the thermodn. stabilization through chelation and delocalization, as well as the kinetic effect resulting from neighboring group participation, enabled the realization of DCRs of a broad range of alcs. ROH (R = Et, cyclohexyl, Bn, etc.), thiols NHRSH, primary amines RNH2, and secondary amines R1NH (R1 = diethylaminyl, piperidin-1-yl, (4-methoxyphenyl)(methyl)aminyl, etc.) exhibiting high efficiency and fast equilibrium The dynamic nature of the system was verified through component exchange, and the switch of DCRs was achieved through the manipulation of substrate selectivity. The investigation of mechanism shed insights on the dependence of reaction pathways on nucleophiles, laying the foundation for future design and application.

DiPucchio, Rebecca C. published the artcileExploiting Natural Complexity: Synthetic Terpenoid-Alkaloids by Regioselective and Diastereoselective Hydroaminoalkylation Catalysis, Application In Synthesis of 5961-59-1, the main research area is regioselective diastereoselective hydroaminoalkylation limonene pinene aniline tantalum urea catalyst.

We report a catalytic and atom-economic approach for the addition of N-Me groups to unactivated alkene-containing terpenes to generate a library of synthetic terpenoid-alkaloids. This catalysis was accomplished using Ta(CH2SiMe3)3Cl2 in combination with a new chiral ureate salt, I, for highly chemo-, regio-, and diastereoselective hydroaminoalkylation reactions. The desired products are easily isolated and purified from unreacted starting materials to give aminated terpenes, e.g., II, in one catalytic step. Starting material enantiopurity is completely retained and stereoselective catalysis results give enantiopure products. Absolute stereochem. was determined by X-ray crystallog. and is consistent with regio- and stereoselective alkene insertion into a catalytically active tantallaziridine intermediate.

Microwave-mediated N-arylation of 4-chloroquinazolines in THF/H2O rapidly and efficiently afforded a library of novel 6-halo-2-phenyl-substituted 4-anilinoquinazolines. The methodol. was compatible with numerous ortho-, meta-, and para-substituted N-methylanilines as well as substituted anilines and furnished the corresponding 4-anilinoquinazolines in good yields. Preliminary screening of the synthesized compounds against tumor cells (HCT-116 and T98G) showed promising antiproliferative properties.
