AbstractA fast, efficient, and clean “on water” synthesis of new Schiffbases and their conversion to spiro compounds undermicrowaveirradiation, as well as in water, is reported. Indol-2,3-diones were reacted separately with various heterocyclic and aromatic amines in water at room temperature to obtain corresponding Schiffbases in high purity and yield. These were then converted into corresponding
