外文摘要：A simple and efficient method for the synthesis of spirooxindole derivatives via a three-component reaction of isatin, 5-aminopyrazole, and 1,3-dicarbonylcompounds (or beta- oxo-benzenepropanenitril e) catalyzed by copper triflate in ethanol is described. The advantages of this method include high efficiency, mild reaction conditions, recoverable catalyst, and environmentally benign conditions.
