N-Substituted oxindoles and 2-indolinethiones can be prepared by lithiation of carboxyl protected N,2-dimethylanilines followed by quenching with CO2 or CS2 respectively. 2-Indolinethione derivatives are also available via demethylation of 2-methylthioindoles, which are prepared by lithiation of N-substituted indoles and treatment with dimethyl disulfide.
