    1,7-cyclo-cis :erythrinan-8-one with ceric ammonium nitrate in methanol gave the appreciable yields of the corresponding 11β-methoxy compounds; these were converted into the natural 11-oxygenated erythrinan alkaloid, erythristemine, in high yield.

    Oxidation of 8-oxoerythrinan and 8-oxo-1, 7-cycloerythrinan derivatives with 2 mol eq of ceric ammonium nitrate in alcohols or acetic acid gave the corresponding 11β-alkoxy or acetoxy compounds in moderate yield. Thus, (±)-3, 3, 15, 16-tetramethoxy-1, 7-cycloerythrinan-2, 8-dione and (+)-erysotramidine gave the corresoponding 11β-methoxy and 11β-acetoxy derivatives on oxidation in methanol and in acetic acid, respectively. Those compounds were respectively converted into (±)-erythristemine and (+)-erythrartine in several steps, thus achieving the total synthesis of these alkaloids.

Each of the sequences developed makes use of photocatalyzed energy transfer processes, which generate singlet oxygen, to set up the substrates for the second photocatalyzed reaction, wherein electron transfer generates carbon‐centered radicals for the cyclizations that give the final complex frameworks.

    The stereochemistry of hydride reduction of erythrinan-7, 8-diones was markedly affected by the bulkiness of the reagent and the polarity of the solvent : sodium borohydride in ethanol-tetrahydrofuran gave the 7β-hydroxy isomers and tetrabutylammounium borohydride in methanol gave the 7α-hydroxy isomers, stereoselectively. This can be explained in terms of fluctuation of the balance between product development control and approach control. The structures of the products were established by chemical and spectroscopic means. Their O-mesylates were hydrolyzed under basic conditions with epimerization to give a mixture of alcohols with a preference for the 7β-hydroxy derivatives. A similar epimerization of the mesyloxy group was also observed in lithium aluminum hydride reduction.
