3-Alkoxy-1H-isoindoles 1 bearing substituents at the carboxylic moiety have been synthesized from substituted 2,3-dihydro-1H-isoindol-1-ones 4 by regiospecific O-alkylation to 5 with trialkyloxonium tetrafluoroborates or methyl trifluoroborates or methyl trifluoromethanesulfonate and subsequent NH deprotonation.According to the spectroscopic properties the semicyclic alkyl imidates 1 exist exclusively in the benzoid 1H structure; the tautomeric o-quinonoid 2H structure 2 cannot be detected by spectroscopic means.
