Regioselective decarboxylative cross-coupling of carboxy isoquinoline N -oxides

A straightforward method for direct decarboxylative arylation of 1- and 3-carboxy isoquinaldic acid N-oxides with aryl iodides is reported. The reaction proceeded selectively at the carboxy function site to exclusively give the corresponding C-1 or C-3 arylated product. This methodology tolerates various aryl iodides substituted by electronically different groups. Combined with subsequent Reissert-Henze chlorination and SNAr amination, the decarboxylative arylation provides an efficient access to 1,3-functionalized isoquinoline-based antitumor agent.

C2-Alkenylation of N-heteroaromatic compounds: Via Br¡ãnsted acid catalysis

Substituted heteroaromatic compounds, especially those based on pyridine, hold a privileged position within drug discovery and medicinal chemistry. However, functionalisation of the C2 position of 6-membered heteroarenes is challenging because of (a) the difficulties of installing a halogen at this site and (b) the instability of C2 heteroaryl-metal reagents. Here we show that C2-alkenylated heteroaromatics can be accessed by simple Br¡ãnsted acid catalysed union of diverse heteroarene N-oxides with alkenes. The approach is notable because (a) it is operationally simple, (b) the Br¡ãnsted acid catalyst is cheap, non-toxic and sustainable, (c) the N-oxide activator disappears during the reaction, and (d) water is the sole stoichiometric byproduct of the process. The new protocol offers orthogonal functional group tolerance to metal-catalysed methods and can be integrated easily into synthetic sequences to provide polyfunctionalised targets. In broader terms, this study demonstrates how classical organic reactivity can still be used to provide solutions to contemporary synthetic challenges that might otherwise be approached using transition metal catalysis.

N-Methylquinolinium derivatives for photonic applications: Enhancement of electron-withdrawing character beyond that of the widely-used N-methylpyridinium

A series of pi-conjugated styryl quinolinium push-pull chromophores have been designed and synthesized in order to examine the electron-withdrawing strength of various quinolinium electron acceptor groups, and their influence on the photophysical properties and in particular on the second-order nonlinear optical response. The static molecular first hyperpolarizabilities measured by long-wavelength hyper-Rayleigh scattering are found to follow the order of the electron withdrawing strength of their acceptor groups as determined by NMR analysis. The quinolinium chromophores based on the strongest electron acceptor groups (1,2- and 1,4-dimethylquinolinium) exhibit remarkably large first hyperpolarizability values of 233 and 256 ¡Á 10-30esu respectively, which is higher than that of the well-known and widely-used pyridinium analogue 4-(4-(dimethylamino)styryl)-1-methylpyridinium 4-methylbenzenesulfonate with first hyperpolarizability = 183 ¡Á 10-30esu. The dimethylquinolinium electron acceptor groups exhibit increased electron-withdrawing strength compared to the dimethylpyridinium group used in 4-(4-(dimethylamino)styryl)-1-methylpyridinium 4-methylbenzenesulfonate, and therefore have a high potential for photonic applications.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: Isoquinolines, you can also check out more blogs about1125-80-0

Minisci-Type C?H Cyanoalkylation of Heteroarenes Through N?O/C?C Bonds Cleavage

A visible-light-induced C?H cyanoalkylation of heteroarenes was described, in which cycloketone oximes were readily transformed into carbon-centered radicals with a terminal cyano-group via N?O/C?C bonds cleavage in one phtochemical step. This reaction protocol displayed a broad substrate scope of heterocycle compounds, and it provided a promising strategy for the installation of cyanoalkyl groups onto heteroarenes.

Copper-Catalyzed C-4 Carboxylation of 1-Naphthylamide Derivatives with CBr4/MeOH

A simple and practical copper catalyzed C-4 carboxylation reaction of 1-naphthylamide derivatives using carbon tetra bromide and methanol is reported here. Picolinamide and its derivatives are used as a bidentate directing group for the distal C4-H functionalization. Various substituted naphthylamide derivatives, and anilides are employed for the carboxylation and proceeds in good yields under mild condition. From the outcome of experimental results, it is proposed that C4-H carboxylation reaction of 1-naphthylamides might proceed through a single electron transfer (SET) pathway. (Figure presented.).

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 486-73-7 is helpful to your research. Electric Literature of 486-73-7
