摘要
A series of new dispiro compounds were synthesized via the three-component 1,3-dipolar cycloaddition reaction of acenaphthenequinone, thiazolidine-4-carboxylic acid and (Z)-5-benzylidene-2-thioxothiazolidin-4-one or (Z)-5-benzylidenethiazolidine-2,4-dione in ethanol under ultrasound irradiation. This protocol has the advantages of mild reaction conditions, high yields and short reaction time.
