Microwave Assisted Synthesis of Some Quinoxaline Derivatives

The high commercial demand for quinoxalines needs a rapid, greener and safer synthetic method among the chemists.A series of quinoxaline derivatives has been synthesized by condensation of diamines and dicarboniles in microwave heating conditions and in solvent free media.This environmentally benign synthetic approach gives us excellent yields (80-90%) in shorter reaction time (3.5 minutes.).The method is cleaner with an easier work-up process.The structures of these synthesized products are based on elemental analysis and mass spectral data.
