THE SYNTHESIS OF RUGOSINONE AND LEDECORINE

Hydrolysis with concomitant air oxidation of polyberbine (5), derived from berberine chloride (6), furnished dihydrorugosinone (7) which underwent further air oxidation in ethanolic sodium hydroxide to give rugosinone (2). m-Chloroperbenzoic acid oxidatio
