Dahiya, Amit published the artcileOrthogonal and Modular Arylation of Alkynylgermanes, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is alkyne preparation chemoselective; alkynylgermane alkynyl silane aryl halide arylation blue light gold.

While alkynyl silanes are ubiquitously employed in synthetic handles, especially in the build-up of more complex alkynes, such as alkyne-based polyaromatic materials, the identification of a similar robust functionality with ideally orthogonal reactivity space would greatly expand the modularity and scope in the construction of functional alkynes. Authors herein disclose the efficient, mild, and modular arylation of alkynylgermanes, which is enabled by blue light-assisted gold catalysis and allows for the chemoselective arylation of the alkynylgermane moiety at room temperature in 2 h over alkynyl silanes, aryl halides, aryl BPin, and various other functional groups. Conversely, the alkynylgermane proved to be uniquely stable toward typical alkynyl silane deprotection conditions as well as Sonogashira cross-coupling conditions, which underlines its orthogonal reactivity space and significant potential as a complementary robust alkyne handle.

Lee, Taegyo published the artcileRhodium-Catalyzed Enantioselective Silylation of Cyclopropyl C-H Bonds, Safety of 1-(4-Fluorophenyl)cyclopropanecarbonitrile, the main research area is rhodium catalyzed enantioselective silylation cyclopropylmethanol ethylsilane; chiral hydroxycyclopropanol preparation crystal structure; mol structure chiral hydroxycyclopropanol; carbon hydrogen bond activation silylation cyclopropylmethanol rhodium catalyst; kinetic isotope effect silylation cyclopropylmethanol rhodium catalyst; C−H activation; asymmetric catalysis; cyclopropanes; rhodium; silylation.

Hydrosilyl ethers, generated in situ by the dehydrogenative silylation of cyclopropylmethanols with diethylsilane, undergo asym., intramol. silylation of cyclopropyl C-H bonds in high yields and with high enantiomeric excesses in the presence of a Rh catalyst derived from a Rh precursor and the bisphosphine (S)-DTBM-SEGPHOS. The resulting enantioenriched oxasilolanes are suitable substrates for the Tamao-Fleming oxidation to form cyclopropanols with conservation of the ee value from the C-H silylation. Preliminary mechanistic data suggest that C-H cleavage probably is the turnover-limiting and enantioselectivity-determining step.

Yao, Hua published the artcileCyanomethylation of the Benzene Rings and Pyridine Rings via Direct Oxidative Cross-Dehydrogenative Coupling with Acetonitrile, SDS of cas: 1885-29-6, the main research area is arylacetonitrile preparation regioselective green chem; arylamine acetonitrile dehydrogenative coupling cyanomethylation.

A novel and efficient approach for the amine-directed dehydrogenative C(sp2)-C(sp3) coupling of arylamines RNH2 (R = Ph, 5-chloropyridin-2-yl, pyrazin-2-yl, etc.) with acetonitrile was reported by using FeCl2 as the catalyst. Arylamines react with inactive acetonitrile to form the corresponding arylacetonitriles R1CH2CN (R1 = 2-amino-5-chloropyridin-3-yl, 2-aminophenyl, 6-amino-1,3-benzothiazol-7-yl, etc.) in moderate to good yields. This protocol features nontoxic iron catalysis, efficient atom economy, nonprefunctionalized starting materials, good regioselectivity, and excellent compatibility of functional groups and aromatic rings, providing a novel, straightforward, and green approach toward arylacetonitriles.

Osinubi, Adejoke published the artcileSynthesis and in vitro anticancer activities of substituted N-(4′-nitrophenyl)-L-prolinamides, Related Products of nitriles-buliding-blocks, the main research area is substituted nitrophenyl prolinamide preparation in vitro anticancer human; aryl proline preparation amine amidation; para fluoronitrobenzene thionyl chloride proline DMF catalyst condensation; anti-cancer agents; biomolecules; carcinoma cell lines; cytotoxicity; pyrrolidine-2-carboxamides.

Synthesis of N-(4′-substituted phenyl)-L-prolinamides I [R1 = CN, NO2; R2 = H, OH; R3 = H, Me, cyclohexyl, etc.; R4 = Pr, cyclohexyl, SO2C6H5, etc.; R3R4 = 4-morpholinyl, 2-isoindolinyl] via amidation reaction of N-aryl-L-prolines II with amines in presence of SOCl2 was described. Intermediate compounds II were obtained by condensation of p-fluoronitrobenzene with L-proline under aqueous-alc. basic conditions. The cytotoxicities of I against four human carcinoma cell lines (SGC7901, HCT-116, HepG2 and A549) were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay; with good tumor inhibitory activities (79.50 ± 1.24%-50.04 ± 1.45%) against HepG2. I [R1 = NO2; R2 = H; R3 = R4 = n-butyl] exhibited the best anti-tumor activity against A549 with percentage cell inhibition of 95.41 ± 0.67% at 100μM. Likewise, I [R1 = NO2; R2 = H; R3 = Me; R4 = Ph] (70.13 ± 3.41%) and I [R1 = NO2; R2 = H; R3 = H; R4 = 4-NO2C6H4] (83.36 ± 1.70%) displayed stronger antineoplastic potencies against A549 than the standard, 5-fluorouracil (64.29 ± 2.09%), whereas I [R1 = NO2; R2 = H; R3 = R4 = n-butyl] (93.33 ± 1.36%) and I [R1 = NO2; R2 = H; R3 = H; R4 = 4-NO2C6H4] (81.29 ± 2.32%) outperformed the reference (81.20 ± 0.08%) against HCT-116. SGC7901 Showed lower percentage cell viabilities with I [R1 = NO2; R2 = H; R3 = H; R4 = 4-NO2C6H4] (8.02 ± 1.54%) and I [R1 = NO2; R2 = H; R3 = R4 = cyclohexyl] (27.27 ± 2.38%). These results underscored the antiproliferative efficacies of L-prolinamides while exposing I [R1 = NO2; R2 = H; R3 = H, Me; R4 = Ph, 4-NO2C6H4] as promising broad-spectrum anti-cancer agents. Structure-activity relationship studies were also discussed.
