## Abstract A novel and highly efficient method for the synthesis of the title oxazine (III) and pyrimidine derivatives (V) under thermal and irradiation microwave conditions is developed.
The environment-friendly three component condensation reactions of N,N%-dimethylbarbituric acid, 4-nitrobenzaldehyde and alkyl or aryl isocyanides to afford the corresponding furo[2,3-d]pyrimidine-2,4(1H,3H)-diones, in water, in high yields after several minutes are reported.
