Author is Li, Qiong; Zhang, Shu-Yu; He, Gang; Ai, Zhaoyan; Nack, William A.; Chen, Gong.

In this report, a highly efficient method for the room temperature installation of alkyl amino motifs onto the ortho position of anilines via Cu-catalyzed carboxamide-directed amination with cyclic alkylamines is described. This method offers a practical solution for the rapid synthesis of complex arylamines from simple starting materials and enables new planning strategies for the construction of arylamine-containing pharmacophores. A single electron transfer (SET)-mediated mechanism is proposed.

COA of Formula: C6H5Cl2NO. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles.

Author is Yang, Qi-Liang; Wang, Xiang-Yang; Lu, Jia-Yan; Zhang, Li-Pu; Fang, Ping; Mei, Tian-Sheng.

Electrochem. oxidation represents an environmentally friendly solution to conventional methods that require caustic stoichiometric chem. oxidants. However, C-H functionalizations merging transition-metal catalysis and electrochem. techniques are, to date, largely confined to the use of precious metals and divided cells. Herein, the authors report the 1st examples of Cu-catalyzed electrochem. C-H aminations of arenes at room temperature using undivided electrochem. cells, thereby providing a practical solution for the construction of arylamines. The use of Bu4NI as a redox mediator is crucial for this transformation. From mechanistic studies including kinetic profiles, isotope effects, cyclic voltammetric analyses, and radical inhibition experiments, the reaction appears to proceed via a single-electron-transfer (SET) process, and a high valent Cu(III) species is likely involved. These findings provide a new avenue for transition-metal-catalyzed electrochem. C-H functionalization reactions using redox mediators.

Application In Synthesis of Picolinoyl chloride hydrochloride. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Picolinoyl chloride hydrochloride, is researched, Molecular C6H5Cl2NO, CAS is 39901-94-5, about Hydroxy-substituted azacalix[4]pyridines: synthesis, structure, and construction of functional architectures.

A number of hydroxyl-substituted azacalix[4]pyridines I (R1 = OH, R2 = R3 = R4 = H; R1 = R3 = OH, R2 = R4 = H; R1 = R2 = R3 = R4 = OH, etc.) were synthesized using Pd-catalyzed macrocyclic ”2 + 2” and ”3 + 1”; coupling methods and the protection-deprotection strategy of hydroxyl group. While the conformation of the these hydroxyl-substituted azacalix[4]pyridines I is fluxional in solution, in the solid state, they adopted shape-persistent 1,3-alternate conformations. Besides, X-ray anal. revealed that the existence of hydroxy groups on the para-position of pyridine facilitated the formation of solvent-bridged intermol. hydrogen bonding for mono-hydroxyl-substituted compound while partial tautomerization for four-hydroxyl-substituted macrocycles, resp. Taking the hydroxyl-substituted azacalix[4]pyridines I as mol. platforms, multi-macrocycle-containing architectures and functional building blocks were constructed. The self-assembly behavior of the resulting building blocks was investigated in crystalline state.

Quality Control of Picolinoyl chloride hydrochloride. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Picolinoyl chloride hydrochloride, is researched, Molecular C6H5Cl2NO, CAS is 39901-94-5, about Anti-selective [3+2] (Hetero)annulation of non-conjugated alkenes via directed nucleopalladation. Author is Ni, Hui-Qi; Kevlishvili, Ilia; Bedekar, Pranali G.; Barber, Joyann S.; Yang, Shouliang; Tran-Dube, Michelle; Romine, Andrew M.; Lu, Hou-Xiang; McAlpine, Indrawan J.; Liu, Peng; Engle, Keary M..

A method that enables direct access to these core structures, e.g., I from non-conjugated alkenyl amides RNHC(O)CH(R2)CH=CHR1 [R = quinolin-8-yl, pyridin-2-yl; R1 = H, Me, Et; R2 = H, CH3, CH2C6H5, 3-CH3OC6H4(CH2)2, (CH2)2OCH2C6H5, (CH2)2CH=CH2] and N-3-buten-1-yl-2-pyridinecarboxamide and ortho-iodoanilines, e.g., 4-iodopyridin-3-amine/phenols II (R3 = Me, Br, t-Bu, etc.; R4 = H, Br; R5 = H, I; X = O) has been described. Under palladium(II) catalysis this [3 + 2] heteroannulation proceeds in an anti-selective fashion and tolerates a wide variety of functional groups. N-Acetyl, -tosyl, and -alkyl substituted ortho-iodoanilines, as well as free -NH2 variants, are all effective. Preliminary results with carbon-based coupling partners like Et 2-cyano-2-(2-iodophenyl)acetate, di-Me 2-(2-iodophenyl)malonate and Et 2-(benzenesulfonyl)-2-(2-iodophenyl)acetate also demonstrate the viability of forming indane core structures III (R6 = C(O)2Me, C(O)2Et; R7 = C(O)2Me, CN, S(O)2Ph) using this approach. Exptl. and computational studies on reactions with phenols support a mechanism involving turnover-limiting, endergonic directed oxypalladation, followed by intramol. oxidative addition and reductive elimination.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Picolinoyl chloride hydrochloride, is researched, Molecular C6H5Cl2NO, CAS is 39901-94-5, about Synthesis of Carbazoles by Copper-Catalyzed Intramolecular C-H/N-H Coupling.Product Details of 39901-94-5.

A Cu-catalyzed intramol. C-H amination for the synthesis of carbazoles has been developed. The key to success is the installation of the picolinamide-based directing group, which is spontaneously removed after the coupling event. The Cu catalysis proceeded smoothly under Pd- and I(III)-free conditions, and its mild oxidation aptitude enables the rapid and concise construction of heteroatom-incorporated carbazole core π-systems.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 39901-94-5, is researched, Molecular C6H5Cl2NO, about Potency and selectivity of trifluoroacetylimino and pyrazinoylimino nicotinic insecticides and their fit at a unique binding site niche, the main research direction is nicotinic receptor selectivity neonicotinoid pharmacophore modification; thiazoline trifluoroacetylimino pyrazinoylimino insecticide nicotinic receptor.Name: Picolinoyl chloride hydrochloride.

Neonicotinoid agonists with a nitroimino or cyanoimino pharmacophore are the newest of the four most important classes of insecticides. Studies on the nicotinic receptor structure in the neonicotinoid-bound state revealed a unique niche of about 6 Å depth beyond the nitro oxygen or cyano nitrogen tip. The N-substituted imino pharmacophore was therefore extended to fill the gap. Excellent target site selectivity with high insecticidal activity and low toxicity to mammals were achieved rivaling those of the current neonicotinoid insecticides as illustrated here by 3-(6-chloropyridin-3-ylmethyl)-2-trifluoroacetyliminothiazoline and its pyrazinoylimino analog.
