Resumen
- A simple method for the synthesis of phenazine and quinoxaline derivatives have been developed via a reaction of o-phenylenediamines and 1,2-dicarbonyl compounds or aryl glyoxals in the presence of lead dichloride in ethanol at room temperature. This method has many appealing attributes such as excellent yields, short reaction times, and simple work-up procedure.
