Substituted Furans

The Friedel–Crafts t-butylation of methyl 2-pyrrolecarboxylate and of 2-acetylpyrrole have been investigated. The results are found to be consistent with the mechanistic pathway suggested in earlier isopropylation papers. Evidence is presented that alkylation of similarly substituted furans may be interpreted in the same way.
