A series of new oxygenated analogues of marine 3‐alkylpyridine alkaloids were prepared from 3‐pyridinepropanol in few steps and in good yields. The key step for the synthesis of these compounds was a Williamson etherification under phase‐transfer conditions. All new compounds were evaluated for their antiplasmodial activity and cytotoxicity. A significant reduction in parasitaemia was observed for some of the prepared compounds, and the majority of them exhibited a selectivity index (SI) ranging from 2.78 to 15.58, which suggests that these compounds may be a promising class of substances with antimalarial activity.
