A facile and environmentally benign procedure for the synthesis of 3-aryl-1 H-spiro[indoline-3′,2-quin-azoline]2′,4(3 H)-dione from isatoic anhydride, aromatic amines and isatin derivatives in Brønsted acidic ionic liquid, 1-methylimidazolium hydrogen sulfate, was reported. The ability to reuse the ionic liquid, the high yield, short reaction time and ease of purification are the important features of this process. [ABSTRACT FROM AUTHOR] |
