## Abstract A series of dispiropyrrolidine derivatives were synthesized via the threeโcomponent 1,3โdipolar cycloaddition reaction of isatin, sarcosine and 5โarylideneโ1,3โthiazolidineโ2,4โdione or 5โarylideneโ4โthioxoโ1,3โthiazolidineโ2โone in ethanol under ultrasound irradiation. This protocol ha
A facile synthesis of novel spiroindane-1,3-diones has been achieved via 1,3-dipolar cycloaddition of an azomethine ylide, generated in situ from ninhydrin and 1,2,3,4-tetrahydroisoquinoline, with the conjugated double bond of chalcone derivatives. The regiochemistry and structures of the cycloadduc
