The reaction of 5-bromo-2-methoxytropone with O- and N-nucleophiles, such as ethanol/potassium carbonate, sodium hydroxide, diethylamine, propylamine, p-chloroaniline/triethylamine, and p-phenylenediamine/triethylamine, gave corresponding 2-O- and 2-N-substituted troponoids. Alkyl diamines reacted with the substrate to produce bis(2-aminotropone)s. In the case of S-nucleophiles as 1-propanethiol, thiophenol
