Abstract

Alkylation of 3-hydroxypyrromethenes and 3-hydroxypyrrole derivatives with trialkyloxoniumtetrafluoborate afforded 3-alkoxy-derivatives whereas other methods of alkylation (dimethyl sulfate, methyl fluorosulfonate, diazomethane) led only to N-methylated compounds. The structure assignments were based on chemical and spectroscopic data.
