Abstract

With acetylacetone in the presence of hydrogen chloride, oxindole and 1-acetyloxindole form mixtures of approximately equal amounts of 3-isopropylideneoxindole, 2,4-dimethyl-1-oxoniacarbazole chloride, and the hydrochloride of methyl o-aminophenylacetate. In the case of other 1- and 5-substituted oxindoles, the 3-isopropylidene derivatives have been isolated.
