Murugesan, Kathiravan published the artcilePhotoredox-Catalyzed Site-Selective Generation of Carbanions from C(sp3)-H Bonds in Amines, Computed Properties of 5961-59-1, the main research area is deuterium tritium labeled amine preparation; amine photoredox catalyst deuterium tritium labeling.

Herein, activation of a C(sp3)-H bond in the α-position to an amine via a carbanion intermediate was described. In the presence of several α-amine sites, only one specific position was selectively activated. Applying this protocol, the proposed carbanion intermediate was effectively trapped with different electrophiles such as deuterium (D+), tritium (T+), or carbonyl compounds compiling over 50 examples. Further, this methodol. was used to install deuterium or tritium in different drug-derivatives (>10 drugs) at a selected position in a late-stage functionalization. In addition, the protocol was suitable for a gram-scale synthesis, and a detailed mechanistic investigation was carried out to support our hypothesis.

Biswas, Nandita published the artcileRu-Catalyzed Selective Catalytic Methylation and Methylenation Reaction Employing Methanol as the C1 Source, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is methylated compound green preparation; phenylethanol methanol methylation ruthenium catalyst; naphthol methanol methylation ruthenium catalyst; amine methanol methylation ruthenium catalyst.

The activity of the acridine-derived SNS-Ru pincer for the activation of methanol to apply it as a C1 building block in different reactions was explored. Catalytic system showed great success toward the β-C(sp3)-methylation reaction of 2-phenylethanols to provide good to excellent yields of the methylated products RCH(CH3)CH2OH [R = Ph, 4-FC6H4, 2-thienyl, etc.]. The mechanistic details, kinetic progress and temperature-dependent product distribution, which revealed the slow and steady generation of in situ formed aldehyde, was the key factor to get the higher yield of the β-methylated product. To establish the environmental benefit of this reaction, green chem. metrics were calculated Furthermore, dimerization of 2-naphthol via methylene linkage to obtain methylated products I [R1 = H, 3-MeO, 6-Ph, etc.] and formation of N-methylation of amine were also described in this study, which offers a wide range of substrate scope with a good to excellent yield of methylated products R2NHCH3 [R2 = (CH2)7CH3, Ph, 2-BrC6H4, etc.].

Das, Kuhali published the artcileManganese-Catalyzed Anti-Markovnikov Hydroamination of Allyl Alcohols via Hydrogen-Borrowing Catalysis, Synthetic Route of 5961-59-1, the main research area is amino alc preparation regioselective chemoselective; allyl alc amine anti Markovnikov hydroamination manganese catalyst.

In this article, a selective formal anti-Markovnikov hydroamination of allyl alcs. RCH=C(R1)C(R2)OH (R = H, Me, n-Pr, pent-4-en-1-yl; R1 = H, Me; R2 = H, Me, Ph, furan-2-yl, etc.) is presented. It enables the versatile synthesis of valuable γ-amino alc. building blocks e.g., 3-(methyl(phenyl)amino)propan-1-ol. A phosphine-free Earth’s abundant manganese(I) complex catalyzed the reaction under hydrogen-borrowing conditions. A vast range of amines such as pyrrolidine, aniline, 1H-indoline, morpholine, etc. drug mols., and natural product derivs e.g., I. underwent successful hydroamination with primary and secondary allylic alcs. with excellent functional group tolerance. The catalysis could be performed on a gram scale and has been applied for the synthesis of drug mols. The mechanistic studies revealed the metal-ligand bifunctionality as well as hemilability of the ligand backbone as the key design principle for the success of this catalysis.

Leischner, Thomas published the artcileHighly selective hydrogenation of amides catalysed by a molybdenum pincer complex: scope and mechanism, Safety of 4-Methoxy-N-methylaniline, the main research area is methyl formanilide molybdenum pincer complex catalyst chemoselective hydrogenation; methylaniline preparation.

A series of molybdenum pincer complexes showed for the first time to be active in the catalytic hydrogenation of amides. Among the tested catalysts, I proved to be particularly well suited for the selective C-N hydrogenolysis of N-methylated formanilides. Notably, high chemoselectivity was observed in the presence of certain reducible groups including even other amides. The general catalytic performance as well as selectivity issues was rationalized taking an anionic Mo(0) as the active species. The interplay between the amide CO reduction and the catalyst poisoning by primary amides accounted for the selective hydrogenation of N-methylated formanilides. The catalyst resting state was found to be a Mo-alkoxo complex formed by reaction with the alc. product. This species played two opposed roles – it facilitated the protolytic cleavage of the C-N bond but it encumbered the activation of hydrogen.

Shen, Meng-Lan published the artcileCounteranion-controlled regioselectivity in palladium-catalyzed allylic amination of dienyl allylic carbonates, Related Products of isoquinoline, the main research area is aryl amine dienyl allylic carbonate palladium catalyst regioselective amination; dienyl aryl amine preparation diastereoselective.

A regioselective Pd-catalyzed allylic amination reaction of dienyl allylic carbonates and aromatic amines has been developed by means of phosphoramidite-palladium catalysis. The regioselectivity could be altered by the counterion of the π-allylpalladium intermediate. As a result, either branched Z-dienyl allylic amines or linear conjugated allylic amines were generated in high levels of regioselectivity from the same substrates by tuning the reaction conditions.

Lenko, Illia published the artcileMedia-Driven Pd-Catalyzed Reaction Cascades with 1,3-Diynamides Leading Selectively to Either Indoles or Quinolines, Application In Synthesis of 5961-59-1, the main research area is diynamide amine palladium catalyst cascade heteroannulation rection; amino alkynyl indole preparation; aminoalkenyl quinoline preparation; cumulenes; homogeneous catalysis; indoles; quinolines; ynamides.

Divergent Pd-catalyzed reaction cascades with various 1,3-diynamides yielding either 2-amino-3-alkynylindoles or 2-amino-4-alkenylquinolines were established. Omitting or adding TBAF (tetrabutylammonium fluoride) to the reaction of N,N-(2-iodophenyl)(4-toluenesulfonyl)-1,3-diynamides with secondary or primary amines in the presence of KOH in THF and catalytic amounts of Pd(PPh3)4 completely changed the outcome of the reaction. In the absence of TBAF, 2-amino-3-alkynylindoles were the sole products, while the presence of TBAF switched the product formation to 2-amino-4-alkenylquinolines. Deuterium labeling proceeded selectively at the C3 and C11 positions of the 2-amino-4-alkenylquinoline products and this suggests the unprecedented formation of [4]cumulenimines from 1,3-diynamides as reactive key intermediates.

Abrams, Roman published the artcileTriarylmethanes and their Medium-Ring Analogues by Unactivated Truce-Smiles Rearrangement of Benzanilides, HPLC of Formula: 5961-59-1, the main research area is preparation triarylmethane medium ring analog; unactivated Truce Smiles rearrangement benzanilide intramol nucleophilic aromatic substitution; Hammett plot; SNAr; Truce-Smiles rearrangement; medium ring; triarylmethane.

Intramol. nucleophilic aromatic substitution (Truce-Smiles rearrangement) of the anions of 2-benzyl benzanilides leads to triarylmethanes in an operationally simple manner. The reaction succeeds even without electronic activation of the ring that plays the role of electrophile in the SNAr reaction, being accelerated instead by the preferred conformation imposed by the tertiary amide tether. The amide substituent of the product may be removed or transformed into alternative functional groups. A ring-expanding variant (n to n+4) of the reaction provided a route to doubly benzo-fused medium ring lactams of 10 or 11 members. Hammett anal. returned a ρ value consistent with the operation of a partially concerted reaction mechanism.

Carbamates, typically used for the protection of amines, including Cbz, Alloc, and Me carbamate, was readily deprotected by treatment with 2-mercaptoethanol in the presence of potassium phosphate tribasic in N,N-dimethylacetamide at 75°C. This nucleophilic deprotection protocol was superior to the standard hydrogenolysis or Lewis acid-mediated deprotection conditions for substrates bearing a functionality sensitive to these more traditional methods.

Li, Yufei published the artcileVisible-Light-Induced Photocatalyst-Free Radical Trifluoromethylation, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is heteroarene trifluoromethyl thianthrenium salt trifluoromethylation; trifluoromethyl heteroarene preparation; hydrazone trifluoromethyl thianthrenium salt trifluoromethylation; trifluoromethylhydrazone preparation; acrylamide trifluoromethyl thianthrenium salt trifluoromethylation; trifluoroethylindolinone preparation.

An attractive, versatile, and operationally simple, visible-light-induced, transition-metal-free, photocatalyst-free, and oxidant-free trifluoromethylation has been demonstrated. Triflic anhydride (Tf2O), being inexpensive and readily available, was chosen as the radical trifluoromethyl source. Thianthrene was used as a recyclable Tf2O-activating reagent, and a high-yielding and scalable trifluoromethylation reaction was achieved. D. functional theory and mechanistic studies showed that a free radical homolytic process excited by visible light is involved in this reaction, generating a key trifluoromethyl radical intermediate.
