Liu, Yue-Jin published the artcileCopper/Silver-Mediated Direct ortho-Ethynylation of Unactivated (Hetero)aryl C-H Bonds with Terminal Alkyne, Related Products of chlorides-buliding-blocks, the publication is Chemistry – A European Journal (2015), 21(1), 205-209, database is CAplus and MEDLINE.

A copper/silver-mediated oxidative ortho-ethynylation of unactivated aryl C-H bonds with terminal alkynes has been developed. The reaction uses the removable PIP [PIP = 2-(pyridin-2-yl)isopropyl] directing group and features broad substrate scope, high functional-group tolerance, and compatibility with a wide range of heterocycles, providing an efficient synthesis of aryl alkynes. E.g., Cu(OAc)₂ and Ag₂CO₃ catalyzed the ethynylation of benzene derivative (I) with CHCTIPS to give 42% II. This procedure highlights the potential of copper catalysts to promote unique synthetically enabling C-H functionalization reactions that lie outside of the current scope of precious metal catalysis.

Li, Xin published the artcileCopper-Mediated Hydroxylation of Arenes and Heteroarenes Directed by a Removable Bidentate Auxiliary, Synthetic Route of 6313-54-8, the publication is Organic Letters (2014), 16(15), 3904-3907, database is CAplus and MEDLINE.

A copper-mediated C-H hydroxylation of arenes and heteroarenes using our newly developed PIP directing group has been developed. This procedure is scalable and compatible with a wide range of functional groups and heteroarenes, providing an operationally simple protocol for the synthesis of o-hydroxybenzamides. The hydroxylation of nicotinamides gave 4-oxo-1,4-dihydropyridine-3-carboxamides selectively. Preliminary mechanistic studies implicate that a basic ligand-enabled, irreversible, rate-determining CMD step is most likely involved in this process.

Liu, Jing-Jing published the artcileDiscovery of Antimetastatic Chiral Ionone Alkaloid Derivatives Targeting HIF-1α/VEGF/VEGFR2 Pathway, Category: chlorides-buliding-blocks, the publication is ChemMedChem (2021), 16(13), 2130-2145, database is CAplus and MEDLINE.

Novel chiral ionone alkaloid derivatives were synthesized and their antimetastatic effects were evaluated in human breast cancer cells using chemotaxis assay. Compared with pos. control LY294002, a PI3 K inhibitor, seven derivatives exhibited significant inhibitory effects against cancer cell migration. Especially, the IC₅₀ for compound I was as low as 0.035±0.004μM. Further investigations on compound I revealed that it could exert inhibitory effects on the adhesion, migration and invasion of MDA-MB-231 cells. The mechanisms for the antitumor metastatic effects of I might be through the inhibition of HIF-1α/VEGF/VEGFR2/Akt pathway, which suppressed the downstream signaling mols., including Akt1/mTOR/p70S6K and Akt2/PKCζ/integrin β1 pathways. Taken together, chiral ionone alkaloid derivative I has the potential to be developed into an antitumor metastatic agent for breast cancer.

Tan, Yun-Xuan published the artcileAn unconventional trans-exo-selective cyclization of alkyne-tethered cyclohexadienones initiated by rhodium(III)-catalyzed C-H activation via insertion relay, Application In Synthesis of 637-07-0, the publication is CCS Chemistry (2021), 3(5), 1582-1595, database is CAplus.

Different from the established trans-endo-selective cyclization of alkyne-tethered electrophiles that involve an E/Z isomerization process, herein, the authors present a novel strategy to allow trans-exo-selective arylative cyclization of 1,6-enynes. Through initiation of rhodium(III)-catalyzed C-H activation, a diverse range of N-heterocyclic directing groups, including pyridine, pyrazole, imidazo[1,2-a] pyridine, benzoxazole, benzothiazole, and purine, was feasible for the cascade transformation, exhibiting high efficiency (up to 92% yield), broad substrate scope, and excellent functional group compatibility. Moreover, the modification of natural products and pharmaceutical compounds was also demonstrated to showcase its synthetic utility. Based on d. functional theory (DFT) calculations, a key three-membered ring intermediate through the insertion relay, rather than the direct E/Z isomerization of alkenyl rhodium species, controlled the stereochem. outcome for this trans-exo-selective cyclization. The subsequent ring-opening protonation of the more favored rotamer led to exclusive trans-exo-selectivity.

An efficient one-pot synthesis of multisubstituted 9,10-dihydrophenanthrenes from easily available 2-arylazaarenes and cyclohexadienone-tethered terminal alkynes (1,6-enynes) has been successfully achieved. This domino reaction proceeded smoothly through Cp*Rh(III)-catalyzed C-H activation, direct protonation of alkenyl-Rh intermediates, intramol. Diels-Alder reaction, alkene isomerization, subsequent ring-opening aromatization, and acetylation. This strategy was pot-economical and tolerated a wide range of functional groups. Moreover, the potent anticancer activities against HepG2 cells were observed for these artificial 9,10-dihydrophenanthrene derivatives

Yu, Fei published the artcilePhotostimulus-Responsive Large-Area Two-Dimensional Covalent Organic Framework Films, Quality Control of 219537-97-0, the publication is Angewandte Chemie, International Edition (2019), 58(45), 16101-16104, database is CAplus and MEDLINE.

Using an external stimulus to modulate the electronic structure of covalent organic frameworks (COFs) is very important because such a response will endow them with addnl. functions. A two-dimensional (2D) COF, constructed from a photo-responsive unit (1,2-bis(5-formyl-2-methylthien-3-yl)cyclopentene), can reversibly switch its elec. conductivity 200 times from low state (the open form) to high state (the closed form) upon irradiation with UV light and reversible with visible light. This reversible phenomenon can be monitored through a circuit containing a light-emitting diode (LED). Photoinduced ring-closing/opening reactions do not destroy the integrity of the frameworks, and both processes follow logarithmic carrier generation with time. Moreover, the correlation between COFs electronic properties and changes in photoinduced kinetics and absorption curves has been demonstrated.

Zhang, Sheng published the artcileA Highly Selective and Potent PTP-MEG2 Inhibitor with Therapeutic Potential for Type 2 Diabetes, Product Details of C8H7ClO3, the publication is Journal of the American Chemical Society (2012), 134(43), 18116-18124, database is CAplus and MEDLINE.

Protein tyrosine phosphatases (PTPs) constitute a large family of signaling enzymes that control the cellular levels of protein tyrosine phosphorylation. A detailed understanding of PTP functions in normal physiol. and in pathogenic conditions has been hampered by the absence of PTP-specific, cell-permeable small-mol. agents. We present a stepwise focused library approach that transforms a weak and general non-hydrolyzable pTyr mimetic (F₂Pmp, phosphonodifluoromethyl phenylalanine) into a highly potent and selective inhibitor of PTP-MEG2, an antagonist of hepatic insulin signaling. The crystal structures of the PTP-MEG2-inhibitor complexes provide direct evidence that potent and selective PTP inhibitors can be obtained by introducing mol. diversity into the F₂Pmp scaffold to engage both the active site and unique nearby peripheral binding pockets. Importantly, the PTP-MEG2 inhibitor possesses highly efficacious cellular activity and is capable of augmenting insulin signaling and improving insulin sensitivity and glucose homeostasis in diet-induced obese mice. The results indicate that F₂Pmp can be converted into highly potent and selective PTP inhibitory agents with excellent in vivo efficacy. Given the general nature of the approach, this strategy should be applicable to other members of the PTP superfamily.
