摘要：

A new method has been developed for regiospecific conversion of substituted anilines to isatins. The method utilizes the reaction of an ortho-lithiated, protected aniline derivative with diethyl oxalate to furnish an alpha-ketoester. Hydrolytic deprotection of the amino moiety is accompanied by cyclization to provide the isatin.
