The indole alkaloid catharanthine (I) is treated with m-chloroperbenzoic acid to provide the N-oxide (II). Condensation of (II) with the alkaloid vindoline (III) under Polonovski reaction conditions leads to the bis-indole adduct (IV), which is further reduced to the tetrahydropyridine compound (V). Catalytic hydrogenation of tetrahydropyridine (V) furnishes (VI). This is then oxidized to the N-oxide (VII) (3).

In a similar procedure, coupling of catharanthine-N-oxide (I) with vindoline (II) under Polonovski reaction conditions leads to the iminium salt (III). This is subsequently converted into the desired enamine (IV) employing NADH as the reducing reagent. Aeration of enamine (IV) in the presence of FeCl3, followed by reductive work up leads to the title compound (4).
