Kumar, Puneet published the artcileMetal-Free Direct Transformation of Aryl Boronic Acid to Primary Amines, COA of Formula: C7H8BClO2, the publication is European Journal of Organic Chemistry (2022), 2022(27), e202200508, database is CAplus.

In this work, a transition-metal free approach for the construction of primary aromatic amines R/R¹NH₂ (R = 4-chlorophenyl, 2H-1,3-benzodioxol-5-yl, naphthalen-2-yl, etc.)/(R¹ = Ph, 4-methylphenyl, 4-hydroxyphenyl, 4-chlorophenyl, 2-cyanophenyl) from aryl boronic acids RB(OH)₂ and esters R¹Bpin with N-Boc-O-tosylhydroxylamine as an amine surrogate was reported. Bench stable TsONHBoc is easy to use and it produces a non-interfering water-soluble byproduct. The protocol is operative for both electron-rich and electron-deficient aryl boronic acids under acidic conditions, wherein, the former arenes affords a better yield of the desired product. Even, sterically hindered and halogenated substrates are easily amenable under this reaction condition. The current protocol can be scaled up to produce gram-scale primary aromatic amines.

Lu, Guo-Liang published the artcileSynthesis and structure-activity relationships for tetrahydroisoquinoline-based inhibitors of Mycobacterium tuberculosis, Computed Properties of 209919-30-2, the publication is Bioorganic & Medicinal Chemistry (2020), 28(22), 115784, database is CAplus and MEDLINE.

A series of 5,8-disubstituted tetrahydroisoquinolines e.g., 2-((5-(4-chlorophenyl)pyridin-2-yl)methyl)-8-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydroisoquinoline were shown to be effective inhibitors of M. tb in culture and modest inhibitors of M. tb ATP synthase. There was a broad general trend of improved potency with higher lipophilicity. Large substituents (e.g., Bn) at the tetrahydroquinoline 5-position were well-tolerated, while N-methylpiperazine was the preferred 8-substituent. Structure-activity relationships for 7-linked side chains showed that the nature of the 7-linking group was important; -CO- and -COCH₂– linkers were less effective than -CH₂– or -CONH- ones. This suggests that the positioning of a terminal aromatic ring is important for target binding. Selected compounds showed much faster rates of microsomal clearance than the clin. ATP synthase inhibitor bedaquiline, and modest inhibition of mycobacterial ATP synthase.

Jiang, Xi published the artcileSynthesis and blue electroluminescent properties of copolymers derived from silafluorene and thiophene, Application of 4-Chloro-2-methylphenylboronic acid, the publication is Gaodeng Xuexiao Huaxue Xuebao (2007), 28(8), 1586-1592, database is CAplus.

Two series of silafluorene based copolymers containing a small molar fraction (1%-3%) of thiophene derivatives moieties were synthesized with Yamamoto coupling reaction: poly {9,9-dihexyl-3,6-silafluorene-co-[2,5-di(phenylene-4-yl)-thiophene]} (PSiF-DPT) and poly {9,9-dihexyl-3,6-silafluorene-co-[2,5-di-((2-methylphenylene)-4-yl)-thiophene]} (PSiF-DMPT). These copolymers were characterized via UV-Vis absorption spectra and photoluminescence spectra. Polymer light-emitting diodes (PLED) were fabricated to investigate these electroluminescent properties. It was found that the thiophene derivatives moieties became the efficient blue emitter via efficient energy transfer from the polysilafluorene segments. With the decrease of the coplanarity of thiophene derivatives or its feed ratio, the PL and EL spectra can be blue shifted. The color purity can be adjusted to CIE (0.19, 0.16) with a EL quantum efficiency of 0.46%.

Hu, Penghui published the artcileBio-inspired iron-catalyzed oxidation of alkylarenes enables late-stage oxidation of complex methylarenes to arylaldehydes, Quality Control of 209919-30-2, the publication is Nature Communications (2019), 10(1), 1-9, database is CAplus and MEDLINE.

A bio-inspired iron-catalyzed polymethylhydrosiloxane-promoted aerobic oxidation of methylarenes to arylaldehydes with high yields and selectivities was reported. Notably, this method can tolerate oxidation-labile and reactive boronic acid group, which is normally required to be transformed immediately after its introduction and represents a significant advance in the area of the chem. of organoboronic acids, including the ability to incorporate both aldehyde and ketone functionalities into unprotected arylboronic acids, a class that can be difficult to access by current means. The robustness of this protocol was demonstrated on the late-stage oxidation of complex bioactive mols., including dehydroabietic acid, Gemfibrozil, Tocopherol nicotinate, a complex polyol structure and structurally complex arylboronic acids.

We report an efficient method for the preparation of various 2,2′-dihalobiaryls from cyclic diaryliodonium salts. With cheap halogen sources as starting materials, a broad range of 2,2′-diiodobiaryls, 2-bromo-2′-iodobiaryls, and 2-chloro-2′-iodobiaryls were obtained under mild reaction conditions. More importantly, a chiral copper-bisoxazoline catalyst system was further developed for the preparation of axially chiral 2,2′-dihalobiaryls in excellent yields and enantioselectivities, which can serve as versatile precursors for the synthesis of various chiral ligands.

An efficient asym. halogenation of cyclic diaryliodonium salts was demonstrated, which gave access to a wide range of axially chiral 2,2′-dihalobiaryls in good to excellent yields and with excellent enantioselectivities. The use of CuX with chiral bisoxazoline ligand and tetrabutylammonium halides in the unique solvent of hexafluoroisopropanol (HFIP) led to the best results in the process. The axially chiral 2,2′-dihalobiaryls was transformed into a number of enantiopure chiral ligands that was potentially useful in asym. catalysis.

An efficient Pd-catalyzed C(sp³)-H selective iodination of 8-methylquinolines I (R = H, Ph, 4-chlorophenyl; R¹ = H, Cl, Ph, etc.; R² = H, F, Cl, Br; R³ = H, Cl, Br, I) is reported herein for the first time. Because of the versatility of organic iodides, the method offers a facile access to various C8-substituted quinolines II. By slightly switching the reaction conditions, an efficient C(sp³)-H acetoxylation of 8-methylquinolines I has also been enabled. Both approaches feature mild reaction conditions, good tolerance of functional groups, and a broad substrate scope.
