Nanoscaled iron oxides on carbon were modified with nitrogen-doped graphene (NGr) and found to be excellent catalysts for the chemoselective transfer hydrogenation of nitroarenes to anilines. Under standard reaction conditions, a variety of functionalized and structurally diverse anilines, which serve as key building blocks and central intermediates for fine and bulk chems., were synthesized in good to excellent yields.

Das, Somnath published the artcileTeaching Old Compounds New Tricks: DDQ-Photocatalyzed C-H Amination of Arenes with Carbamates, Urea, and N-Heterocycles, Application In Synthesis of 18585-06-3, the publication is Chemistry – A European Journal (2017), 23(72), 18161-18165, database is CAplus and MEDLINE.

The C-H amination of benzene derivatives was achieved using DDQ as photocatalyst and BocNH₂ as the amine source under aerobic conditions and visible light irradiation Electron-deficient and electron-rich benzenes react as substrates with moderate to good product yields. The amine scope of the reaction comprises Boc-amine, carbamates, pyrazoles, sulfonimides and urea. Preliminary mechanistic studies indicate arene oxidation by the triplet of DDQ to radical cations with different electrophilicity and a charge transfer complex between the amine and DDQ as intermediate of the reaction.

Nakajima, Yusuke published the artcileAuxin transport and response requirements for root hydrotropism differ between plant species, Synthetic Route of 33697-81-3, the publication is Journal of Experimental Botany (2017), 68(13), 3441-3456, database is CAplus and MEDLINE.

The direction of auxin transport changes in gravistimulated roots, causing auxin accumulation in the lower side of horizontally reoriented roots. This study found that auxin was similarly involved in hydrotropism and gravitropism in rice and pea roots, but hydrotropism in Lotus japonicus roots was independent of both auxin transport and response. Application of either auxin transport inhibitors or an auxin response inhibitor decreased both hydrotropism and gravitropism in rice roots, and reduced hydrotropism in pea roots. However, Lotus roots treated with these inhibitors showed reduced gravitropism but an unaltered or an enhanced hydrotropic response. Inhibiting auxin biosynthesis substantially reduced both tropisms in rice and Lotus roots. Removing the final 0.2 mm (including the root cap) from the root tip inhibited gravitropism but not hydrotropism in rice seedling roots. These results suggested that modes of auxin involvement in hydrotropism differed between plant species. In rice roots, although auxin transport and responses were required for both gravitropism and hydrotropism, the root cap was involved in the auxin regulation of gravitropism but not hydrotropism. Hydrotropism in Lotus roots, however, may be regulated by a novel mechanism that is independent of both auxin transport and the TIR1/AFBs auxin response pathway.

Padwa, Albert published the artcileDichloroketene-Induced Cyclizations of Vinyl Sulfilimines: Application of the Method in the Synthesis of (±)-Desoxyeseroline, Application In Synthesis of 7080-50-4, the publication is Journal of Organic Chemistry (2005), 70(21), 8538-8549, database is CAplus and MEDLINE.

The reactions of several aryl-, furanyl-, and vinyl-substituted sulfilimines, e.g. I, with dichloroketene proceeded at 25 °C to yield thioalkyl-substituted γ-lactams, e.g. II. The overall process involves nucleophilic addition of the nitrogen atom of the sulfilimine onto the highly electrophilic dichloroketene to first generate a zwitterionic intermediate. A subsequent [3,3]-sigmatropic rearrangement is followed by intramol. trapping of the Pummerer cation by the amido anion to furnish the observed γ-lactam product. Incorporation of donor groups on the aromatic ring of the sulfonyl functionality had little effect when aryl-substituted sulfilimines were used but exhibited a major effect on the efficiency of the reaction with furanyl-substituted systems. The placement of an electron donor group (i.e., OMe) on the sulfonyl aryl group enhances the nucleophilicity of the amido anion contained within the sulfonium ion intermediate and facilitates the rate of the 3,3-sigmatropic rearrangement. Styryl-substituted sulfilimines cyclize in a stereospecific manner and produce a 3:2-mixture of γ-lactams and the isomeric imino-lactone system. The heavily functionalized γ-lactams are easily converted to a variety of nitrogen containing substrates. The vinyl sulfilimine cyclization method was applied to the total synthesis of the Calabar alkaloid (±)-desoxyeseroline (III).

Zhao, Jinpeng published the artcileChemoselective methylene oxidation in aromatic molecules, Safety of 3-Chloro-4-hydroxyphenylacetic acid, the publication is Nature Chemistry (2019), 11(3), 213-221, database is CAplus and MEDLINE.

Despite significant progress in the development of site-selective aliphatic C-H oxidations over the past decade, the ability to oxidize strong methylene C-H bonds in the presence of more oxidatively labile aromatic functionalities remains a major unsolved problem. Such chemoselective reactivity is highly desirable for enabling late-stage oxidative derivatizations of pharmaceuticals and medicinally important natural products that often contain such functionality. Here, we report a simple manganese small-mol. catalyst Mn(CF₃-PDP) system that achieves such chemoselectivity via an unexpected synergy of catalyst design and acid additive. Preparative remote methylene oxidation is obtained in 50 aromatic compounds housing medicinally relevant halogen, oxygen, heterocyclic and biaryl moieties. Late-stage methylene oxidation is demonstrated on four drug scaffolds, including the ethinylestradiol scaffold where other non-directed C-H oxidants that tolerate aromatic groups effect oxidation at only activated tertiary benzylic sites. Rapid generation of a known metabolite (piragliatin) from an advanced intermediate is demonstrated.

Type 2 diabetes is at epidemic proportions and thus development of pharmaceutical therapies for improving insulin sensitivity has become of paramount importance. The objectives of the current study were to develop novel dual PPARγ/δ agonists without the deleterious side effects associated with full PPARγ agonists and several compounds were made and evaluated.. Biol. evaluation of compounds was accomplished by transcriptional promoter activity assays, quant. PCR gene anal. for known PPARγ/δ targets as well as in vitro assays for lipid accumulation and mitochondrial biogenesis verses known PPAR agonists. It was found that compound I was the most potent and selective dual PPARγ/δ agonist which did not display the deleterious side effects associated with full PPARγ agonists.

Me 6-butyl-2-methyl-4-oxo-7-(2-phenoxyethoxy)-1,4-dihydroquinoline-3-carboxylate (I, ICI 56,780) displayed causal prophylactic and blood schizonticidal activity (ED₅₀ = 0.05 mg/kg) in rodent malaria models but produced rapid acquisition of parasitol. resistance in P. berghei infected mice. Herein we describe the synthesis of analogs of I with EC₅₀ as low as 0.15 nM against multidrug resistant P. falciparum. Optimal activity with low cross-resistance indexes (RI) to atovaquone was achieved by introducing ortho-substituted aryl moieties at the 3-position of the 7-(2-phenoxyethoxy)-4(1H)-quinolone core.

Ring-opening cyclization of cyclohexane-1,3-dione-2-spirocyclopropanes I (R = H, Me, Ph; R¹ = H, Me; R² = H, Ph, 4-methylphenyl, 4-bromophenyl, n-butyl; n = 1) using dimethylsulfoxonium methylide proceeded regioselectively to produce 2,3,4,6,7,8-hexahydro-5H-1-benzopyran-5-ones II (R³ = H; n = 1) in good to high yields. The reactions of cycloheptane- and cyclopentane-1,3-dione-2-spirocyclopropanes I (R = H; R¹ = H; R² = phenyl; n = 0 or 2) could construct [7.6]- and [5.6]-fused ring systems II (R³ = H; n = 0 or 2). This reaction was also carried out using triethyl(oxo)-sulfanylium chloride, tributyl(oxo)-sulfanylium chloride, and benzyldimethyloxo-sulfanylium chloride, resulting in the formation of the corresponding 2,3-trans-disubstituted products III (R⁴ = Ph; R⁵ = Me, Pr, phenyl) and II (R = H; R¹ = H; R² = H; R³ = Ph; n = 1) in good to high yields, and it was shown that the di-Me group can act as a dummy substituent.
