A novel cascade reaction of aryl aldoxime with dimedone under microwave irradiation:: The synthesis of N-hydroxylacridine

A novel sequential addition, elimination and cyclization reactions took place when aldoxime and dimedone in glycol was subjected to microwave irradiation and a new type of N-hydroxylacridinedione derivatives was obtained in excellent yields (80-95%) within a short reaction time (4-8 min).
