One-pot synthesis of heteroaryl and diheteroaryl ketones through palladium-catalyzed 1,2-addition and oxidation
A synthetic method was developed for the preparation of heteroaryl and diheteroaryl ketones from aldehydes and organoboronic acids through a palladium-catalyzed 1,2-addition and oxidation that uses an aryl iodide as the oxidant. This one-pot process shows high tolerance for a broad range of heterocyclic substrates by using 1.0-3.0 mol-% of the catalyst that is formed from allylpalladium chloride dimer and a thioether-imidazolinium chloride. In addition to fine-tuning the catalytic system, the use of a sterically hindered aryl iodide that has a substituent at the ortho position, such as 2-iodotoluene, is important to obtain the desired ketones with heterocyclic moieties in good to excellent yields. The one-pot synthesis of heteroaryl and diheteroaryl ketones was achieved by a palladium-catalyzed 1,2-addition and oxidation. This catalytic process with 1.0-3.0 mol-% catalyst loading tolerates a broad range of heterocyclic substrates to give ketones with heterocyclic moieties in good to excellent yields. Copyright
