Synthesis of 2-Hydroxy-3,10,11-trimethoxy-5,6,13,13a-tetrahydro-8H-dibenzoquinolizine (Govanine)

Condensation of 6,7-dimethoxy-3-isochromanone (1) with 3-methoxy-4-benzyloxy-β-phenethylamine (2) gives N-(3-methoxy-4-benzyloxy-β-phenethyl)-4,5-dimethoxy-2-hydroxymethylphenylacetamide (3).Treatment of 3 with POCl3 followed by NaBH4 reduction and debenz

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)
