• Lithiation occurs at the 2-position. Excess n-BuLi in the presence of TMEDA leads to 2,5-dimetallation: J. Chem. Soc. Perkin I, 887 (1977).
• Reaction of benzenoid aromatics with lactones under Friedel-Crafts conditions normally results in alkylation. With 1-methylpyrrole and - or δ-lactones in the presence of AlCl3, acylation at the 2-position predominates: Tetrahedron Lett., 36, 6739 (1995).
