An efficient synthesis of novel dispirooxindoles has been achieved through three-component 1,3-dipolar cycloaddition of azomethine ylides generated in situ by the decarboxylative condensation of isatin and an α-amino acid with the dipolarophile 5-benzylid

5-(Benzylidene- and o-chlorobenzylidene-) and cinnamylidene-hydantoins reacted with chlorosulfonic acid to give the corresponding p-sulfonyl chlorides (1, 35, 44).These were converted into 49 derivatives by reaction with amines, hydrazines and azide ion.
