ABSTRACT:
Preparing oxindoles and intermediates therefor by reacting an N-haloaniline with .beta.-thio esters or .beta.-thio amides to form an azasulfonium halide, reacting the azasulfonium halide with a base to form an ortho-[thioether (hydrocarbonoxycarbonyl) alkyl]aniline, or a [thioether (aminocarbonyl) alkyl]aniline, reacting the orthosubstituted 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.
