PROCESS FOR PREPARING 3,3-DISUBSTITUTED OXINDOLES AND THIO-OXINDOLES

摘要

Methods for preparing oxindole and thio-oxindole compounds are provided, which compounds are useful as precursors to useful pharmaceutical compounds. Specifically provided are methods for preparing 5-pyrrole-3,3-oxindole compounds and 5-(7-fluoro-3,3-dimethyl-2-oxo-2,3-dihydro-lH-indol-5-yl)-l-methyl-lH-pyrrole-2-carbonitrile. Also provided are methods for preparing iminobenzo[b]thio?hene and benzo[b]thiophenone compounds.
