Oxidation of paZmatine CL) choride with m-chtoroperbenzoic acid in methyZene chloride in the presence of sodium bicarbonate at near -78' C yieZds polycarpine (2-j. A new biogenetic route to the aporphines is proposed which does not invoZve phenoZic oxidative coupling, and proceeds through the intermediacy of protoberberinium saZts.
