| titleOfInvention | Synthesis of oxindoles from anilines and intermediates therein |
| abstract | Preparing oxindoles and intermediates therefor by reacting an N-haloaniline with β-thio esters or β-thio amides to form an azasulfonium halide, reacting the azasulfonium halide with a base to form an ortho-[thio-ether (hydrocarbonoxycarbonyl) alkyl]aniline, or a [thio-ether (aminocarbonyl) alkyl]aniline, reacting the ortho-substituted aniline with an acid to form a 3-thio-ether-2-oxindole, and then reducing the 3-thio-ether-2-oxindole with Raney Nickel to form the 2-oxindole. |
