摘要
To one pot synthesis of coumarins with benzimidazol or benzoxazol moieties, three different microwave irradiations based procedures are reported here which take place within a few minutes. In spite of fairly well yield of the products using solvent free procedures, 25-30% further yields were achieved within 3 minutes at 110 degrees C using 2mL n-pentanol as solvent.
