A general copper-catalyzed enantioconvergent C(sp³)-C(sp) cross-coupling of diverse racemic tertiary alkyl halides RX [R = 1-cyclohexyl-1-[(naphthalen-1-yl)carbamoyl]ethyl, 1-phenyl-1-(phenylcarbamoyl)propyl, 1-[(4-bromophenyl)carbamoyl]-1-phenylpropyl, etc.; X = Cl, Br] and I (R¹ = Et, cyclopropyl, benzyl, etc.; R² = Et, Ph, 3-bromophenyl, etc.) with terminal alkynes R³CCH (R³ = Ph, cyclohexen-1-yl, thiophen-2-yl, etc.) (87 examples) was demonstrated. Key to the success is the rational design of chiral anionic N,N,N-ligands, e.g., II (R⁴ = t-butylphenyl) tailor-made for the computationally predicted outer-sphere radical group transfer pathway. This protocol provides a practical platform for the construction of chiral C(sp³)-C(sp/sp²/sp³) bonds, allowing for expedient access to an array of synthetically challenging quaternary carbon building blocks of interest in organic synthesis and related areas.

Skrodzki, Maciej;Ortega Garrido, Victor;Csaky, Aurelio G.;Pawluc, Piotr research published 《 Searching for highly active cobalt catalysts bearing Schiff base ligands for Markovnikov-selective hydrosilylation of alkynes with tertiary silanes》, the research content is summarized as follows. The search for simple and easy-to-synthesize ligands for bench stable cobalt (pre)catalysts that would ensure high activity and selectivity in alkyne hydrosilylation reactions is an interesting current challenge. Herein, we report that a cobalt(II) complex bearing pyrimidine-imine-2H-imidazole ligand activated by LiHBEt₃ exhibits not only high catalytic activity, but also unprecedented tolerance towards tertiary silanes in highly regioselective Markovnikov hydrosilylation of aliphatic and aromatic terminal alkynes to give α-vinylsilanes. In addition, a variety of 1-aryl-2-(trimethylsilyl)acetylenes have been hydrosilylated efficiently by diphenylsilane in the presence of [Co(L)Cl₂]/LiHBEt₃ catalytic system to yield (E)-1-aryl-1,2-bis(silyl)ethenes with high selectivity. Such selectivity is very rarely observed for cobalt-catalyzed hydrosilylation of silylacetylenes.

Strauss, Marie E.;Santaloci, Taylor J.;Fortenberry, Ryan C. research published 《 Valence-, Dipole- and Quadropole-Bound Electronically Excited States of Closed-Shell Anions Formed by Deprotonation of Cyano- and Ethynyl-Disubstituted Polycyclic Aromatic Hydrocarbons》, the research content is summarized as follows. Dicyano-functionalized benzene and naphthalene anion derivatives exhibit a relatively rich population of electronically excited states in stark contrast to many assumptions regarding the photophysics of anions in general. The present work has quantum chem. analyzed the potential electronically excited states of closed-shell anions created by replacing hydrogen atoms with valence-bound lone pairs in benzene and naphthalene difunctionalized with combinations of -CN and -C₂H. Dicyanobenzene anion derivatives can exhibit dipole-bound excited states as long as the cyano groups are not in para position to one another. This also extends to cyanoethynylbenzene anions as well as deprotonated dicyano- and cyanoethynylnaphthalene anion derivatives Diethynyl functionalization is less consistent. While large dipole moments are created in some cases for deprotonation on the -C₂H group itself, the presence of electronically excited states beyond those that are dipole-bound is less consistent. Beyond these general trends, 2-dicyanonaphthalene-34 gives strong indication for exhibiting a quadrupole-bound excited state, and the 1-cyanoethynylnaphthalene-29 and -36 anion derivatives are shown to possess as many as two valence-bound excited states and one dipole-bound excited state. These photophys. properties may have an influence on regions where polycyclic aromatic hydrocarbons are known to exist such as in various astrochem. environments or even in combustion flames.

Su, Lebin;Xie, Shimin;Dong, Jianyu;Pan, Neng;Yin, Shuang-Feng;Zhou, Yongbo research published 《 Copper-Catalyzed 6-endo-dig Cyclization-Coupling of 2-Bromoaryl Ketones and Terminal Alkynes toward Naphthyl Aryl Ethers in Water》, the research content is summarized as follows. The cyclization-coupling reaction of 2-bromoaryl ketones 2-Br-4-R-5-R¹C₆H₂C(O)Me (R = H, Cl, F, MeO; R¹ = H, Cl, Me), 1-(pyridin-3-yl)ethan-1-one and terminal alkynes R²CCH (R² = Ph, 4-bromophenyl, pyridin-3-yl, etc.) is first realized by copper catalysis, which produces polyfunctional naphthyl aryl ethers I (X = CH, N) in moderate to excellent yields with broad substrate scope and good functional group tolerance. This reaction proceeds via 6-endo-dig cyclization and C(sp²)-O coupling using green H₂O as the unique solvent and 5-bromopyrimidin-2-amine as the critical additive. Mechanistically, a unique Cu(III)-acetylide probably is the key intermediate, which allows exclusive 6-endo-dig selectivity.

Sun, Yaru;Tang, Xiaochan;Li, Xiaobing;Kong, Xiuqi;Tian, Minggang;Wang, Yue;Dong, Baoli research published 《 PET-ESIPT-based fluorescent probes for revealing the fluctuation of peroxynitrite (ONOO^–) in living cells, zebrafishes and brain tissues》, the research content is summarized as follows. Peroxynitrite (ONOO^–) plays crucial roles in a variety of physiol. and pathol. processes in living systems, and therefore, real-time and in situ imaging of ONOO^– is of great significance to in-depth study its biol. roles. Herein, we have developed PET-ESIPT-based fluorescent probes (BCN and BCN-A) for the detection of ONOO^– in living cells, zebrafishes and brain tissues. BCN was a highly sensitive ONOO^– probe in which the fluorescence property of the fluorophore was simultaneously controlled by PET and ESIPT mechanisms, and transformed to BCN-A via acetylation. Especially, BCN showed large Stokes shift in response to ONOO^–, and displayed high selectivity to ONOO^–. BCN-A employed the acetate group to switch off ESIPT process of the fluorophore and improve the membrane permeability. In living cells, BCN-A released an ONOO^–-responsive probe (BCN) by the hydrolysis of esterase, and then detected ONOO^–. Biol. imaging demonstrated that although both metformin and rotenone are mitochondrial complex I inhibitors, metformin can increase the generation of ONOO^– while rotenone had no significant influence on the generation of ONOO^– in living cells and zebrafishes. Moreover, the amygdala and perirhinal/entorhinal cortex in the brain of depressive mouse both showed increasing fluorescence intensity relative to those of normal mouse, which suggested that the LPS-induced depressive disorder could result in the generation of ONOO^– in the two brain areas of mouse. We expect that the probes (BCN and BCN-A) could extensively serve as the powerful mol. tools to investigate the biol. roles of ONOO^– for the in-depth study of drug mechanism and depressive disorder.

Tatevosyan, Stepan S.;Kotovshchikov, Yury N.;Latyshev, Gennadij V.;Lukashev, Nikolay V.;Beletskaya, Irina P. research published 《 Facile Access to Triazole-Fused 3,1-Benzoxazines Enabled by Metal-Free Base-Promoted Intramolecular C-O Coupling》, the research content is summarized as follows. A convenient approach to assemble 1,2,3-triazole-fused 4 H-3,1-benzoxazines I (R = H, 6-Me, 7-I, 7,8-dimethoxy, etc.; R¹ = H, Me, Ph; R² = Bu, cyclopropyl, Ph, etc.) has been developed. Diverse alc.-tethered 5-iodotriazoles II (R³ = H, 6-Me, 5-I, 4,5-dimethoxy, etc.), readily accessible by a modified protocol of Cu-catalyzed (3+2)-cycloaddition, were utilized as precursors of the target fused heterocycles I. The intramol. C-O coupling proceeded efficiently under base-mediated transition-metal-free conditions, furnishing cyclization products I in yields up to 96%. Suppression of the competing reductive cleavage of the C-I bond was achieved by the use of Na₂CO₃ in acetonitrile at 100°C. This practical and cost-effective procedure features a broad substrate scope and valuable functional group tolerance.

Treat, Anny;Henri, Vianie;Liu, Junke;Shen, Joyce;Gil-Silva, Mauricio;Morales, Alejandro;Rade, Avaneesh;Tidgewell, Kevin Joseph;Kolber, Benedict;Shen, Young research published 《 Novel TRPV1 Modulators with Reduced Pungency Induce Analgesic Effects in Mice》, the research content is summarized as follows. Capsaicin, the compound in hot chili peppers responsible for their pungency and an agonist of the transient receptor potential cation channel, subfamily V, member 1 (TRPV1), has long been known to promote the desensitization of nociceptors at high concentrations This has led to the utilization and implementation of topical capsaicin cream as an analgesic to treat acute and chronic pain. Critically, the application of capsaicin cream is limited due to capsaicin′s high pungency, which is experienced prior to analgesia. To combat this issue, novel capsaicin analogs were developed to provide analgesia with reduced pungency. Analogs reported in this paper add to and show some differences from previous structure-activity relationship (SAR) studies of capsaicin-like mols. against TRPV1, including the necessity of phenol in the aromatic “A-region”, the secondary amide in the “B-region”, and modifications in the hydrophobic “C-region”. This provided a new framework for de novo small-mol. design using capsaicin as the starting point. In this study, we describe the synthesis of capsaicin analogs, their in vitro activity in Ca²⁺ assays, and initial in vivo pungency and feasibility studies of capsaicin analogs YB-11 and YB-16 as analgesics. Our results demonstrate that male and female mice treated with YB capsaicin analogs showed diminished pain-associated behavior in the spontaneous formalin assay as well as reduced thermal sensitivity in the hotplate assay.
