200 μl (50 μmol) of a 0.25 M solution of each of the isatins listed in Table 1, in dioxane; 200 μl (50 μmol) of a 0.25 M solution of the α-amino acids listed in Table 2, in water (including 1 equivalent of sodium hydroxide for the L-phenylalanine, L-leucine, O-benzyl-(D,L)-serine, L-tryptophan, L-isoleucine, and O-methyl-L-tyrosine); and 400 μl (50 μmol) of a 0.125 M solution containing the chalcones produced by reaction of the arylaldehydes and acetophenone compounds of Tables 3 and 4, in dioxane, were combined in 1 ml perfume vials. The vials were capped and heated at 80° C. overnight. The solvent was then evaporated under reduced pressure and the resulting products were all recovered in greater than 85% purity according to high pressure liquid chromatography (HPLC) and mass spectroscopy (MS) experiments.
