Abstract
A reaction of appropriate indol-2,3-diones with 4-aminoantipyrine has resulted in the formation of hitherto unknown 3-(2,3-dimethyl-5-oxoI-phenyl-3-pyrazolin-4-yl-imino)-indol-2-ones in quantitative yields which upon cyclocondensation with mercaptoacetic acid afforded a series of new spiro heterocycles 3'-(2,3-dimethyl-5-oxo-1-phenyl-3pyrazolin-4-yl) spiro[3H-indol-3,2-thiazolidine]-2,4-diones.
