Lewis acid catalyzed indole synthesis via intramolecular nucleophilic attack of phenyldiazoacetates to iminium ions.

ABSTRACT: Lewis acids catalyze the cyclization of methyl phenyldiazoacetates with an ortho-imino group, prepared from o-aminophenylacetic acid, to give 2,3-substituted indoles in quantitative yields.
