We describe the synthesis of the novel 2-(1,5-dimethyl-4-oxo-hexyl)-3-hydroxy-5-methyl-6-pyrrolyl-1,4-
benzoquinone 2 from the natural product perezone 1. The anion–guest properties of the new compound were evaluated in
the presence of fluoride, chloride, bromide and iodide tetrabutylammonium salts using 1H NMR titration techniques in
deuterated dichloromethane or dimethylformamide. The title compound showed interesting colorimetric behavior in the
presence of inorganic salts.
