Abstract: The present invention pertains to the technical field of synthesis and application of novel compounds, and discloses a synthesis method for aryl ethers substituted ortho to nitrogen in nitrogen-containing heterocycles. Under the catalysis of hexamethylphosphoramide (HMPA), using N,N-diisopropylethylamine (DIEA) as a base and with the assistance of POBr3, the method employs nitrogen oxides to react with phenols, thereby achieving ortho-aryloxy substitution on nitrogen heterocycles. The method of the invention exhibits excellent atom economy (3a, 96%), green solvent selection (using ethyl acetate as solvent), mild reaction conditions, short reaction times (most substrates react within 5 minutes), broad substrate scope, and inexpensive and readily available starting materials. This method provides a convenient, efficient, green, and practical approach for synthesizing 1-aryloxyisoquinolines, 2-aryloxyquinolines, and 2-aryloxypyridine compounds.
