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.
标题化合物是通过巯基乳酸与Isatin-3-imines的环缩合反应制得的。将5'-甲基-3'-苯基-螺基[3 H-吲哚-3,2'-噻唑烷] -2,4'(1 H)-二酮进行曼尼希缩合,得到1-取代的衍生物。除一个例外,所有产品在抗惊厥筛查中均处于非活性状态。
