, 2-benzyloxytropone, 2-(p-tolylmethoxy)tropone, 2-(4-bromophenylmethoxy)tropone, 2-(4-chlorophenylmethoxy)tropone, 2-(4-methoxyphenylmethoxy)tropone, and 2-(1-naphthylmethoxy)tropone, rearranged upon heating to the 3-and 5-arylmethyltropolones via the radical intermediates. Similarly, 5-bromo-2-(p-tolylmethoxy)tropone gave 5-bromo-3-(p-tolylmethyl)tropolone.

The synthesis and in vitro antiparasitic activity of twenty‐seven novel diazabicycles based on tropolone ethers is presented. The compounds can be readily prepared by means of a high‐yielding hetero Diels–Alder reaction using simple and readily available starting materials. Several of the new diazabicycles have in vitro activities against Trypanosoma cruzi, Leishmania donovani, Trypanosoma brucei rhodesiense
