Studies on Tetrahydroisoquinolines. Part 15. Lead Tetra-acetate Oxidation of Four Hydroxytetrahydroprotoberberines, (+/-)-Govanine, (+/-)-Discretine, (+/-)-Corytencine, and (+/-)-10-Hydroxy-2,3,11-trimethoxytetrahydroprotoberberine

Lead tetra-acetate oxidation of (+/-)-2- (1) and (+/-)-10- (2) hydroxytetrahydroprotoberberines afforded the p-quinol acetates (5) and (6), which on treatment with acetic anhydride-concentrated sulphuric acid gave (+/-)-2,5β- (35), and (+/-)-10,13α- (40)
