Decarboxylative Hydroalkylation of Alkynes

The merger of open- and closed-shell elementary organometallic steps has enabled the selective intermolecular addition of nucleophilic radicals to unactivated alkynes. A range of carboxylic acids can be subjected to a CO2 extrusion, nickel capture, migratory insertion sequence with terminal and internal alkynes to generate stereodefined functionalized olefins. This platform has been further extended, via hydrogen atom transfer, to the direct vinylation of unactivated C-H bonds. Preliminary studies indicate that a Ni-alkyl migratory insertion is operative.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 166591-85-1 is helpful to your research. Synthetic Route of 166591-85-1

Cross-dehydrogenative C(sp3)-C(sp3) coupling: Via C-H activation using magnetically retrievable ruthenium-based photoredox nanocatalyst under aerobic conditions

In the present work, we report the fabrication of a highly versatile ruthenium-based magnetically recoverable photoredox nanocatalyst with a large surface area. This visible light harvesting nanocatalyst was effectively used for cross-dehydrogenative coupling via C-H activation between tertiary amines and various carbon nucleophiles with high regioselectivity to afford the C-C coupled products in good to excellent yield using air as an oxidant under ambient conditions. The Ru-based catalyst was found to be a potential candidate from economical and environmental perspectives due to its magnetic recoverability and reusability.

Luminescent 3D Lanthanide-Cadmium Heterometal-Organic Frameworks with Chemical Stability and Selective Luminescent Sensing

Four novel three-dimensional (3D) 4d-4f heterometal-organic compounds, [LnCd2(Pbc)4(Meimdc)(H2O)]¡¤3H2O (Ln = Eu, 1a; Tb, 1b; Sm, 1c; Dy, 1d) (HPbc = 4-(4-pyridinyl)benzoic acid; H3Meimdc = 2-methyl-1H-4,5-imidazole-dicarboxylic acid), have been successfully prepared by a hydrothermal method. All the compounds are isostructural and show three-dimensional microporous pillar-layered structures with uncoordinated carboxylate sites hung in the channels. Compound 1a possesses excellent chemical stability. The luminescent investigations show that compounds 1a, 1b, 1c, and 1d display the characteristic emission bands of Ln3+ ions. Compound 1a exhibits a good potential as a luminescent sensor material for multi-responsive Ag+, Cu2+, Zn+, Co2+, and Ni2+ cations and some organic amines. Interestingly, 1a can capture Ag+, Cu2+, Zn+, Co2+, and Ni2+ cations and shows cation-dependent colorimetric response, which indicates the potential for naked sensing.

Targeting P-glycoprotein: Investigation of piperine analogs for overcoming drug resistance in cancer

P-glycoprotein (P-gp) is a drug transporter that effluxes chemotherapeutic drugs and is implicated in the development of resistance of cancer cells to chemotherapeutic drugs. To date, no drug has been approved to inhibit P-gp and restore chemotherapy efficacy. Moreover, majority of the reported inhibitors have high molecular weight and complex structures, making it difficult to understand the basic structural requirement for P-gp inhibition. In this study, two structurally simple, low molecular weight piperine analogs Pip1 and Pip2 were designed and found to better interact with P-gp than piperine in silico. A one step, acid-amine coupling reaction between piperic acid and 6,7-dimethoxytetrahydroisoquinoline or 2-(3,4-dimethoxyphenyl)ethylamine afforded Pip1 and Pip2, respectively. In vitro testing in drug resistant P-gp overexpressing KB (cervical) and SW480 (colon) cancer cells showed that both analogs, when co-administered with vincristine, colchicine or paclitaxel were able to reverse the resistance. Moreover, accumulation of P-gp substrate (rhodamine 123) in the resistant cells, a result of alteration of the P-gp efflux, was also observed. These investigations suggest that the natural product analog ? Pip1 ((2E,4E)-5-(benzo[d][1,3]dioxol-5-yl)-1-(6,7-dimethoxy-3,4-dihydroisoquinolin-2(1 H)-yl)penta-2,4-dien-1-one) ? is superior to piperine and could inhibit P-gp function. Further studies are required to explore the full potential of Pip1 in treating drug resistant cancer.

Synthesis of 3-Benzazepines by Metal-Free Oxidative C?H Bond Functionalization?Ring Expansion Tandem Reaction

A metal-free synthesis of biologically important benzazepines is achieved through a single synthetic operation involving an oxidative C?H bond functionalization and ring expansion with diazomethanes as key reagent. This represents a new, strong methodology for the straightforward construction of the seven-ring N-heterocyclic structures under mild conditions using a 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxoammonium salt as oxidant. Moderate to good yields are achieved from simple, readily available tetrahydroisoquinolines, and this methodology has been further successfully applied for the synthesis of the 3-benzazepine drug Lorcaserin. A possible mechanistic pathway for the ring expansion step, comprising the extrusion of nitrogen in a concerted asynchronic process, is proposed based on both mechanistic proof and density function theory (DFT) calculations. (Figure presented.).
