- Electron-rich five-membered heterocyclic acid and method for decarboxylation and fluorination of derivative thereof
-
The invention provides electron-rich five-membered heterocyclic acid and a method for decarboxylation and fluorination of derivatives thereof. High-efficiency decarboxylation and fluorination are performed on the electron-rich five-membered heterocyclic acid with different kinds of electron-rich five-membered heterocycles connected with carboxylic acid directly, and the derivatives of the electron-rich five-membered heterocyclic acid, An obtained product has high yield and the process is simple.

- Decarboxylative Fluorination of Electron-Rich Heteroaromatic Carboxylic Acids with Selectfluor
-
A transition-metal-free decarboxylative fluorination of electron-rich five-membered heteroaromatics, including furan-, pyrazole-, isoxazole-, thiophene-, indole-, benzofuran- and indazolecarboxylic acids, with Selectfluor is reported. Fluorinated dimer products were observed for nitrogen-containing heteroaromatic carboxylic acids, such as indole and pyrazole. An effective method has been developed to synthesize the monomer of 2- and 3-fluoroindoles with Li2CO3 as base at low temperature.

- Electrosynthesis of fluorinated indole derivatives
-
Anodic fluorination of various N-acetyl-3-substituted indole derivatives was successfully carried out in Et4NF-4HF/MeCN to provide the corresponding trans-2,3-difluoro-2,3-dihydroindoles exclusively or selectively. Treatment of difluorinated products with a base provided monofluoroindole derivatives or monofluoroindoline derivative depending on the substituents at the 3-position.

- A synthesis of 3-fluoroindoles and 3,3-difluoroindolines by reduction of 3,3-difluoro-2-oxindoles using a borane tetrahydrofuran complex
-
A borane tetrahydrofuran complex has been used to study the reduction of 3,3-difluoro-2-oxindoles and been found to yield either 3-fluoroindoles or 3,3-difluoroindolines. The latter have been found to be reasonably stable when the aromatic nucleus is subs
