ABSTRACT
[structure] Various substituted pyridines can be prepared regioselectively by a sequence involving an intramolecular thermal or high-pressure Diels-Alder cycloaddition of an oximino malonate dienophile tethered to a dienic carboxylic acid, followed by mild aromatization of the resulting cycloadduct with cesium carbonate in DMF at room temperature.
