Synthesis of tetra- and pentasubstituted benzenes from dimedone and derivatives
Nelson,Nelson
, p. 1287 - 1290 (2007/10/02)
Treatment of dimedone (5,5-dimethylcyclohexane-1,3-dione) and derivatives with one molar equivalent of sulfuric acid in trifluoroacetic anhydride leads, via sulfonation and a 1,2-methyl group migration, to a variety of dimethylresorcinol derivatives. The
