The title compounds have been prepared, by the cyclocondensation of thiolactic acid with isatin-3-imines. 5′-Methyl-3′-phenyl-spiro[3H-indole-3,2′-thiazolidine]-2,4′(1H)-dione has been subjected to the Mannich condensation to give 1-substituted derivatives. With one exception, all of the products were inactive in an anticonvulsant screen.
