Abstract

<jats:title>Abstract</jats:title> <jats:p>Pyrrole reacted with vinyl ketones in the presence of 3 mol % of iron(II) tetrafluoroborate or alumina-supported iron(III) perchlorate to give multipoint-alkylated products in good yield. Most notably, 4,5-dialkylated 2-acetylpyrrole was obtained in good yield when 2-acetylpyrrole was allowed to react with an excess amount of vinyl ketones.</jats:p>
