A polymer including a self-immolative polymer segment and a thermally-activated trigger moiety is described. The self-immolative polymer segment includes a head end, a tail end, and a plurality of repeating units. The trigger moiety includes a cycloaddition adduct that is covalently coupled to the head end of the self-immolative polymer segment. When the polymer is exposed to an activation temperature, the cycloaddition adduct undergoes retro-cycloaddition to release the self-immolative polymer segment. The self-immolative polymer segment then decomposes to sequentially release repeating units in a head-to-tail direction.

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
