13C NMR Spectra of some 1-, 3- and 4-Monosubstituted and Disubstituted Isoquinolines

Chemical shifts and substituent chemical shift (SCS) effect are reported for 21 monosubstituted isoquinolines, carrying a halogeno, amino, piperidino or ethoxy group in position 1, 3 or 4.In some cases,assignments of 13C resonances were based on the spectra of the corresponding 5-deutero derivatives.For the fluoroisoquinolines some 13CF coupling constants are given.The 13C NMR spectra of 15 disubstituted isoquinolines were measured; with a few exceptions, mainly the 3,4- and 1,4-disubstituted isoquinolines, the chemical shifts agreed well with those calculated by addition of the SCS effects

A General and Efficient Synthesis of 2-Pyridones, 2-Quinolinones, and 1-Isoquinolinones from Azine N-Oxides

2-Pyridones, 2-quinolinones, and 1-isoquinolinones are critical building blocks in medicinal chemistry. These N-heterocycles, however, remain a challenge to synthesize by current methods. A mild, general, and efficient approach for the synthesis of these hydroxyl N-heteroarenes was developed by employing bromotripyrrolidinophosphonium hexafluorophosphate (PyBroP) as an activating agent and sodium acetate/water as the base/nucleophile combination. The reaction mechanism, especially the dual function of sodium acetate as the base and nucleophile, has been proposed on the basis of results from isotopic labeling experiments.

A highly practical and convenient halogenation of fused heterocyclic N-oxides

A novel, simple and practical method for the regioselective halogenation of fused heterocyclic N-oxides has been developed. It employs Vilsmeier reagent, generated in situ by POX3and DMF, as both the activating agent and the nucleophilic halide source. The method is amenable across a broad range of substrates, including quinolines, isoquinolines and the diazine N-oxides, possessing a variety of substitution patterns. Furthermore, all of the reagents associated are cheap and easy to obtain. The potential extension of this method to a one-pot oxidation/halogenation sequence that obviates the need for isolation of the N-oxide intermediates is also presented.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. 51206-40-7, In my other articles, you can also check out more blogs about 51206-40-7
