hydroxymethyl and benzyl substituted pyridines 2. Attack of the pyridinium chlorides 3 with pyridylcarbonyl hydrazides or benzoyl hydrazides 4 gave the isolable 2,4-dinitroanilino derivative 5 which underwent hydrolysis when refluxed in water:p-dioxane mixture (1:4 v/v) to afford the pyridinium ylides 6. Sodium borohydridereduction of 6 in absolute ethanol at 0° for 4–6 hours resulted in the isolation

A series of oxygenated analogues of marine 3‐alkylpyridine alkaloids were synthesized, and their leishmanicidal activity was assayed. All compounds were prepared from 3‐pyridinepropanol in few steps and in good yields. The key step for the synthesis of these compounds was a classic Williamson etherification under phase‐transfer conditions. Besides toxicity in peritoneal macrophages, the compounds exhibited
