Abstract

Spiro[3H-indole-3,2’-thiazolidine]-2,4’(1H)-diones have been obtained by the condensation of indole-2,3-dione, aromatic amine and mercaptoacetic acid without isolating the intermediates i.e., isatin-3-anils. The spiro compounds have further been subjected to Mannich reaction, acetylation and chloracetylation. All the synthesized compounds have been characterized on the basis of elemental analyses and ir and pmr.
