Insights into the triple self-condensation reaction of thiophene-based methyl ketones and related compounds

The acid catalysed triple self-condensation of 1-thien-2-ylethanone (2-acetylthiophene) and five related compounds is presented. Tetrachlorosilane used as the Lewis acid produces dry hydrogen chloride which catalyzes the self-condensation process. Depending on the reaction conditions and the substitution of the carbonyl substrates, the reaction can proceed as a [2+2+2] cyclotrimerization towards C3-symmetric 1,3,5-trisubstituted benzenes, or as the single-type aldol condensation leading to 1,3-disubstituted (E)-β-methylchalcones. This is important for the design of new aromatic/olefinic compounds beyond the model structures. Synthesis of 4′-fluoro-3,5-di-(2-thienyl)biphenyl through a mixed-type aldol reaction using erbium triflate is discussed. Mechanistic rationale is provided.
