A recent report by Brossi (1) on the seleotive acid-catalpaed demethylation of the methoxyl group substituted m to a carbonyl function prompts this report of similar work. We were interested in developing a method for the seleotive, stepwise demethylation of the aoridoae alkaloid melioopiciae, (I),

The problem of the N-demethylation of quaternary ~onium salts has bee a perennial one in organic chemistry. The classical method for demethylatio Involves the pyrolysis of ammonium halides, which may however lead to extens deoomposition. 2 Refluxing ethanolamine has also been used for purpqeee of
