A series of compounds bearing an endocyclic -N-O- moiety with potentialantimalarial activity based on simple derivatives of the tropolone purpurogallin was prepared by means of a hetero Diels-Alder reaction using nitrosobenzene as a dienophile. The rationale behind the design of these compounds is presented, together with the synthetic route to derivatives bearing aromatic and aliphatic esters of

The preparation and evaluation as potential anti-protozoal agents of molecules bearing an endocyclic hydrazine moiety is presented. The synthetic route to this new series of compounds is straightforward, involving a hetero Diels-Alder reaction between different benzotropolone esters and diethyl azodicarboxylate (DEAD). While they show limited or no in vitro activity against Leishmania donovani, Plasmodium
