Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 34941-92-9, is researched, Molecular C5H3ClFN, about Access to Highly Substituted 7-Azaindoles from 2-Fluoropyridines via 7-Azaindoline Intermediates, the main research direction is azaindole preparation; azaindoline preparation regioselective electrophilic substitution bromination nitration oxidation; fluoronitroethylpyridine preparation oxidative Nef reaction reductive amination intramol SNAr; nitroolefin fluoropyridine metalation addition.COA of Formula: C5H3ClFN.
A versatile synthesis of 7-azaindoles e. g., I, from substituted 2-fluoropyridines is described. C3-metalation and 1,4-addition to nitroolefins provide substituted 2-fluoro-3-(2-nitroethyl)pyridines. A facile oxidative Nef reaction/reductive amination/intramol. SNAr sequence furnishes 7-azaindolines. Finally, optional regioselective electrophilic C5-substitution (e.g., bromination or nitration) and subsequent in situ oxidation delivers highly functionalized 7-azaindoles in high overall efficiency.
